A senior accounting major at Midsouth State University has job offers from four CPA firms. To explore the offers further, she asked a sample of recent trainees how many months each worked for the firm before receiving a raise in salary. The sample information is submitted to Minitab with the following results: Analysis of Variance df Source SS MS P Factor 3 37.68 12.56 8.97 0.133 14 19.54 Error 1.40 Total 17 57.22 What is the decision rule? (Round your answer to 2 decimal places.) Reject HO if F > At the 0.01 level of significance, is there a difference in the mean number of months before a raise was granted among the four CPA firms? O Reject O Do not reject

Fund the mean and variance for the following sample data 12, 16, 11, 23, 9, 17, 12, 25

Consider the following data: 5,−5,5,−5,−5,14,55,−5,5,−5,−5,14,5 Copy Data Step 1 of 3 :   Calculate the value of the sample variance. Round your answer to one decimal place.

An athletic shoemaker wants to test if their new running shoe specially made for sprinting is better than the competition. To do this, they recruit 35 NCAA sprinters and time their 100-meter dash wearing the company's shoe and then time their 100-meter dash again wearing the competitor’s shoe. The difference of these times is then calculated asTimecompany.shoe−Timecompetitor.shoe. The sample mean difference in times is 0.53 seconds and the sample standard deviation is 1.1. Conduct a hypothesis test at theα=0.1 level. (a) Set up the null and alternative hypothesis (using mathematical notation/numbers AND interpret them in the context of the problem) (b) Calculate the test statistic (c) Calculate the critical value. (d) Draw a picture of the distribution of the test statistic underH0. Label and provide values for the critical value and the test statistic, and shade the critical region. (e) Make and justify a statistical decision at theα= 0.15 level and state your conclusions in the…
