A public health official is studying differences in drinking habits among students at two different universities. They collect data from a random sample of students from each of the two universities and ask each student how many alcoholic drinks they consumed in the previous week. Key data are summarized in the table below: Number of drinks in previous week sample size (n) sample mean sample std. dev. (s) University 1 49 6.70 2.10 University 2 49 5.90 2.10 Use the provided information to perform a two-sample t-test to determine whether the mean number of drinks per week for students at University 1 is not equal to the mean number of drinks per week for students at University 2. Based on the given information, using the appropriate formula and the provided Standard Normal Table (Z table), determine the p-value for this hypothesis test. You will need to calculate the test statistic fırst. Enter the p-value in the space below as a decimal rounded to four decimal places:
