Solved by verified expert:You manage Human Relations for your
company. One of your sales managers has retired, leaving an opening. You
are considering two different employees for the position. Both are
highly qualified so you have decided to evaluate their sales performance
for the past year.Use the Week 4 Data Set to create and calculate the following in Excel®:Determine the range of values in which you would expect to find the
average weekly sales for the entire sales force in your company 90% of
the time.Calculate the impact of increasing the confidence level to 95%?Calculate the impact of increasing the sample size to 150, assuming
the same mean and standard deviation, but allowing the confidence level
to remain at 90%? Based on the calculated confidence interval for weekly sales on the sample of 50 reps at a 90% confidence level:Calculate both Reps’ average weekly performance and highlight if it is greater than the population mean. You want to determine whether there is a statistically different average weekly sales between Sales Rep A and Sales Rep B.Create Null and Alternative Hypothesis statements that would allow
you to determine whether their sales performance is statistically
different or not.Use a significance level of .05 to conduct a t-test of independent
samples to compare the average weekly sales of the two candidates.Calculate the p-value?Considering that individual you did not promote:Determine whether this person’s average weekly sales are greater
than the average weekly sales for the 50 sales reps whose data you used
to develop confidence intervals.Create Null and Alternative Hypothesis statements that would allow
you to determine whether the new Sales Manager’s weekly average sales
are greater than the sample of Sales Reps.Use a significance level of .05 to conduct a t-test of independent samples to compare the average weekly sales of both.Calculate the p-value?
