![In the 2018 GSS, a random sample of 1419 adults were asked how many hours per week they
usually spend on email. The mean number of hours spent on email for the sample was 7.15,
with a standard deviation of 11.75. Use these data to calculate a 95% confidence interval for the
mean number of hours spent on email in the population, and answer the following questions
based on those calculations.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F11eeaaf7-4ce7-45d3-84d3-f895e5160d98%2Fd92768eb-fab6-4cf9-bab4-5d4a1d96dfd7%2Febjc89k_processed.jpeg&w=3840&q=75)
