Pyramid Lake is in Nevada. The lake is famous for cutthroat trout. It has been widely advertised that the average length of trout caught in Pyramid Lake isµ = 19 inches. In a recent sample, however, of a random sample of 55 fish caught from the lake, the mean length was 18.5 inches with a standard deviation of 3.2 inches. Can it beclaimed that the average length of a trout caught from Pyramid Lake is less than 19 inches? Use a significance level of α = 0.01. 1. Which of the following would be the correct null and alternative hypothesis for this problem? [null] a. Ho:

A study is to be done to compare the mean time spent on electronic devices for a sample of 45 residents of Santa Monica who are 12 years old and a sample of 45 residents of Santa Monica who are 18 years old. The sample of residents aged 12 years had a mean of 3.1 hours per day with a standard deviation of 1.4 hours per day. The sample of residents aged 18 years old had a mean of 4.3 hours per day with a standard deviation of 1.3 hours per day. At the 0.05 level of significance test the claim that the mean for 12 year old residents is lower than the mean for 18 year old residents. 1. Which of the following would be the correct null and alternative hypothesis for this problem? [null] a. Ho:
