RESPONSE GUIDELINESRespond to at least two peers. Focus on the obstacles or barriers within the data and describe how validity, reliability, outdated data, or inconsistent definitions might hinder the data processing.Student post down below:The Organization that will be discussed is Riverbend City. The City is experiencing a high poverty rate with a lot of issues with employment, graduation rates and a lack of resources to help the struggling north side of the City. The data is being reviewed of the African American’s and Latino’s youth that are dropping out of high school. The youth are confused with dropping out of High School and not getting an education that can lead them to a better life and legal employment. Instead, the youth are dropping out of school to sell drugs and getting expelled from High School. In which these youth’s end up in the Juvenile Justice System. (Riverbend City, 2021)The problem that needs to be considered is starting with the youth home life and providing resources that can help parents of these youth by offering of resources for education and employment. If the parents are knowledgeable, this would roll over to the youth of this city. It will take the assistance from home, school and the community over all to make a change. Data may not be correct of the number of students experiencing these hardship issues in the African American culture and the Latino culture which could bring problems of validity. (Salganik,2018)Knowing that data is not always reliable, looking at the problem of this growing epidemic collaborating with a team of many talents and cultures a determine of how these programs will be provided to the community such as job fairs, training for employment sessions, college opportunities/scholarships, free classes, on the job training, recruiters that can come to the high schools to offer orientations for what is being look at in entry level employment opportunities is where the resources will begin. (Salganik,2018)According to (Guenole, 2007), some challenges, the data may not be accurate. Understanding if there is data is missing, having an assessment to determine what are the age group of these students. The population of African Americans and the populations of Latino families in the city. Even though keeping the data private. The responders can skip questions so that no one will know who is answering these questions. However, the solutions are utilizing the data and preventing what is going to bring success to River bend City. Even though there is missing outdated data. Solving the challenges and having someone that has experience of this review will make sure updated data will be presented once the assessments are completed. This will be a continuous endeavor.

Quality Associates, Inc., a consulting firm, advises its clients about sampling

Quality Associates, Inc., a consulting firm, advises its clients about sampling and statistical procedures that can be used to control their manufacturing processes.In one particular application, a client gave Quality Associates a sample of 800 observations taken during a time in which that client’s process was operating satisfactorily. The sample standard deviation for these data was .21; hence, with so much data, the population standard deviation was assumed to be .21.Quality Associates then suggested that random samples of size 30 be taken periodically to monitor the process on an ongoing basis. By analyzing the new samples, the client could quickly learn whether the process was operating satisfactorily.When the process was not operating satisfactorily, corrective action could be taken to eliminate the problem. The design specification indicated the mean for the process should be 12. The hypothesis test suggested by Quality Associates follows.H0: µ=12Ha: µ≠12Corrective action will be taken anytime H0 is rejected.The following samples were collected at hourly intervals during the first day of operation of the new statistical process control procedure. These data are available in the data set Quality.Managerial Report Conduct a hypothesis test in R for each sample at the .01 level of significance and determine what action, if any, should be taken. Provide the test statistic and p-value for each test.
Compute the standard deviation for each of the four samples in R. Does the assumption of .21 for the population standard deviation appear reasonable?
In R Compute limits for the sample mean around μ = 12 such that, as long as a new sample mean is within those limits, the process will be considered to be operating satisfactorily. If exceeds the upper limit or if is below the lower limit, corrective action will be taken. These limits are referred to as upper and lower control limits for quality control purposes.
Discuss the implications of changing the level of significance to a larger value. What mistake or error could increase if the level of significance is increased?

“`{r load tables1to4, message=FALSE, warning=FALSE}# your code here“`### Table 2On page 307 the authors write:”Table 2 controls for **individual fixed effects** by showing how, on average, the messengers’ revenues deviate from their person-specific mean revenues. Thus, a positive number here indicates a positive deviation from the person-specific mean; a negative number indicates a negative deviation.”>**[Q12]** Fixed effects are a way to control for *heterogeneity* across individuals that is *time invariant.* Why would we want to control for fixed effects? Give a reason how bike messengers could be different from each other, and how these differences might not vary over time.“`{block q12, type = ‘written_answer’}[your written answer here]“`>**[Q13]** Create a variable called `totrev_fe` and add it to the dataframe. This requires you to “average out” each individual’s revenue for a block from their average revenue: $x_i^{fe} = x_{it} – bar{x}_i$ where $x_i^{fe}$ is the fixed effect revenue for $i$.“`{r q13}# your code here“`>**[Q14]** Use `summarise()` to recreate the findings in Table 2 for “Participating Messengers” using your new variable `totrev_fe`. (You do not have to calculate the differences in means.) >> In addition to calculating the fixed-effect controled means, calculate the standard errors. Recall the standard error is $frac{s_{jt}}{sqrt{n_{jt}}}$ where $s_{jt}$ is the standard deviation for treatment $j$ in block $t$ and $n_{jt}$ are the corresponding number of observations. >> (Hint: use `n()` to count observations.) Each calculation should be named to a new variable. Assign the resulting dataframe to a new dataframe called `df_avg_revenue`. “`{r q14}# your code here“`>**[Q15]** Plot `df_avg_revenue`.

Assign it to object `m1`. Recreating this model requires you to control for individual fixed effects and estimate the following equation where $text{H}$ is the variable `high`, $text{B2}$ is the second block (`block == 2`) and $text{B3}$ is the third block (`block == 3`):$$y_{ijt} – bar{y}_{ij} = beta_1 (text{H}_{ijt} – bar{text{H}}_{ij}) + beta_2 (text{B2}_{ijt} – bar{text{B2}}_{ij}) + beta_3 (text{B3}_{ijt} – bar{text{B3}}_{ij}) + (varepsilon_{ijt} – bar{varepsilon}_{ij})$$
