B. The test statistic is round to two decimal places as needed.C. The critical value/values are round two decimal places as needed use, to separate answers as needed.D. Because the test statistic _________ we ____ the null hypothesis.E. The P value is round to three decimal places as needed.F. We reject or do not reject the null hypothesis G. What assumptions need to be made in order to perform this procedure? A. Although the sample size and the second sample is large enough it must be assumed that the distribution for the first sample is normally distributed and the samples are independent. B. It must be assume that the distribution for both populations are normally distributed and that the samples are independent C. Although the sample size in the first sample is large enough it must be assume that the distribution for the second population is normally distributed and that the samples are independent. D. Since the sample sizes are large enough no Sumption's are needed. What answer is correct?

B. The test statistic is round to two decimal places as needed.C.

Question Help A transportation agency would like to compare the average amount of time it takes passengers to pass through airport security at two locations during peak times. The following table summarizes in minutes the results of two random samples from each airport. Use the table to complete parts a through c. Location 1 Location 2 Sample mean 14.5 11.6 Sample standard deviation 5.5 4.6 Sample size 24 27 a. Perform a hypothesis test using a = 0.05 to determine if the average time to pass through security in location 1 is more than the average time to pass through security in location 2. Assume the population variances for time through security at these two locations are equal. Determine the null and alternative hypotheses for the test. Ho: H1 - H2 Hy: Hi - H2 0 VI V
