Question 13 (12 points) Listen The average number of hours that Canadians spend on the internet at home has been 90 hours per month for several years. In early March of 2020, as more people were starting to work and study at home, a random sample of 16 households found a mean of 96 hours with a sample standard deviation of 10 hours. The population standard deviation is unknown. Assume that hours spent on the internet are approximately normally distributed. Is there enough evidence to conclude that the average number of hours spent on the internet at home has increased? Test the hypothesis at the 5% level of significance. Part 1 (3 marks): What are the null and alternative hypotheses? A. Ho: H = 90 hours HA: M # 90 hours B. Ho: H = 90 hours HA: M 90 hours ( is more than 90 hours) D. Ho: H > 90 hours HA: M = 90 hours E. Ho: N = 96 hours HA: M > 96 hours Enter the LETTER of the correct answer Part 2 (4 marks): MacBook Air 80 DO DD F3 F4 F5 F6 F7 F8 F9 F10 F11 % & 4 5 6 8 9 O R T Y U O P
