Please give the statement form for each

Using the statement and relation form, formulate the null and alternative hypotheses for each of the following: 1. Brown Sugar House restaurant is attempting to determine whether their weekday lunch business has changed with their new menu. Previously, the average revenue per weekday lunch was Php 107,400. A random sample of 25 weekdays after the menu change resulted in a mean revenue of Php 109850. Has the revenue changed significantly if the sample standard deviation is Php 12,210? 2. One of the leading companies in the Philippines is concerned that the quality of graduates they interview for permanent jobs may be decreasing. Last year, the average grade point average (GPA) of overall applicants interviewed was 3.32. This year, the first 145 applicants interviewed had an average GPA of 3.25. If these 145 students are considered at random sample, is the company's concern justified? Assume that the population standard deviation is 0.19
