(Score for Question 1: of 5 points) 1. The average commute times for employees of a large company is 22 minutes. The commute employees are 20, 33, 27, 35, 18, 29, 40, 22, 18, 55, 13, and 14. a) Determine the sample mean and the population mean. b) What is the estimated margin of error of the sample population, using standard deviation a) Sample mean: 26 minutes/ population mean:22 minutes b) PLEASE EXPLAIN ​

The null and alternate hypotheses are: h0: μ1 ≤ μ2 h1: μ1 > μ2 a random sample of 22 items from the first population showed a mean of 113 and a standard deviation of 12. a sample of 16 items for the second population showed a mean of 99 and a standard deviation of 6. use the 0.01 significant level. find the degrees of freedom for unequal variance test. (round down your answer to the nearest whole number.) state the decision rule for 0.010 significance level. (round your answer to 3 decimal places.) compute the value of the test statistic. (round your answer to 3 decimal places.) what is your decision regarding the null hypothesis? use the 0.01 significance level.
