Megan would like to test whether the average commute time is noticeably different for students at two different high schools in her city, using a significance level of 0.05. In a sample of 41 students at High School 1, she gets a sample mean of 21.1 minutes and a sample standard deviation of 3.6 minutes. In a sample of 61 students at High School 2, she gets a sample mean of 17.5 minutes and a sample standard deviation of 4.4 minutes. Assume the population variances are equal. (a) What are the null and alternative hypotheses? Ho: M1 - 12 + HA: H1 - 12 4 (b) What is the test statistic? (Round your answer to 3 decimal places, if needed.) 4.104 Your last answer was interpreted as follows: 4.104 (c) Using the statistical table, the p-value is 0
