Most soft drink beverages are packaged and sold in 12-ounce cans. You want to test to see howaccurate the companies package these cans, so you take a sample of Coke cans and a sample ofPepsi cans and measure the amount of soda in each can.You wish to test the claim that the mean amount of liquid in Coke cans is less than the meanamount of liquid in Pepsi cans at a significance level of a = 0.05.a) Choose the correct null and alternative hypotheses.Ho: 12Ha:μι>μεO Ho: 1-2Ha: 1*2O Ho: 122Ha:μι<μ2Both populations are normally distributed, with cans of Coke having a population standarddeviation of 0.065 and cans of Pepsi having a population standard deviations of 0.071. Your sampleof 52 cans of Coke gave a mean of 12.01 ounces, while your sample of 51 cans of Pepsi gave amean of 12.1 ounces.b) What is the test statistic for this sample?

According to previous studies, the mean distance each visitor in Greenspan National Park hikes during their visit is 30 kilometers. The park recently closed its shuttle system, which used to transport hikers to many of the park's most popular hiking trails. Because of this, an administrator at the park suspects the mean distance, u, is now less than 30 kilometers. The administrator chooses a random sample of 45 visitors. The mean distance hiked for the sample is 27.2 kilometers. Assume the population standard deviation is 9.9 kilometers. Can the administrator conclude that the mean distance hiked by each visitor is now less than 30 kilometers? Perform a hypothesis test, using the 0.10 level of significance. (a) State the null hypothesis H, and the alternative hYpothesis H,. O
