Do government employees take longer coffee breaks than private sector workers? That is a question thatinterested a management consultant. To examine the issue, he took a random sample of ten governmentemployees and another random sample of ten private sector workers and measured the amount of time (inminutes) they spent in coffee breaks during the day. The results are listed below. Assume that the twopopulations are normally distributed.

The work week for adults in the US that work full time is normally distributed with a mean of 47 hours. A newly hired engineer at a start-up company believes that employees at start-up companies work more on average then most working adults in the US. She asks 12 engineering friends at start-ups for the lengths in hours of their work week. Their responses are shown in the table below. Test the claim using a 5% level of significance.

8. A confidence interval for estimating the mean An industrial/organizational psychologist wants to improve worker productivity for a client firm, but first he needs to gain a better understanding of the life of the typical white-collar professional. Fortunately, he has access to the 2008 Workplace Productivity Survey, commissioned by LexisNexis and prepared by WorldOne Research, which surveyed a sample of 650 white-collar professionals (250 legal professionals and 400 other professionals). One of the survey questions was, “How many work-related emails do you receive during a typical workday?” For the subsample of legal professionals (n = 250), the mean response was M = 36.7 emails, with a sample standard deviation of s = 23.8 emails. The estimated standard error is sMM? = A-0.085, B-1.341, C-0.095 or D-1.505 (choices to choose from.) . Use the following Distributions tool to develop a 90% confidence interval estimate of the mean number of work-related emails legal…

Part 1: Hypothesis Test for the Mean- Manual Tasks• Define your concern of interest drawing upon your variables in your dataset.• Conceptualize your null and alternate hypotheses based on your testing concept.a. Apply 1 one-sided test (upper-tail or lower-tail) and 1 two-sided test concepts for the mean with unknown population standard deviation (�) at 1%, 5%, or 10% levels of significance (choose one of them for each test) by stating the appropriate decision rule. b. Calculate p-value for each of your tests and perform testing for your same hypotheses with p-value solution. Comment on how p-value changes for 1%, 5%, and 10% significance levels (for all three).**Here in order to apply normal distribution approximation, it would be better if you choose your sample size greater than 100 (n>100).c. Make a confidence interval estimation for the population mean with unknown variancebased on 90%, 95% and 99% confidence levels and make interpretations for all three. Data is: Name…
