A newspaper director intends to study the amount of time that the readers spend on reading the newspaper. She picks a sample of 28 individuals who read the newspapers on-line. The mean sample turns out to be 20, with standard deviation of 6 hours per month. Another sample of 35 individuals who read the newspapers in paper form. The mean sample for this group is 24, with standard deviation of 8 hours per month.

Given these two samples, run a test to verify if these two groups spend statistically different amount of time on reading the newspaper, at 5% significance level. (Assume the two populations have the same variance.)

Part 1: The amount of time that users of a real estate website spend on the site is believed to be normally distributed. Suppose 20 randomly-selected users of the site were asked how much time they typically spend on the site during the week, and the sample mean was found to be 5.2 hours. (5 pts.) If the population standard deviation is known to be σ=2.8 hours, then What is the point estimate for µ in this problem? Find the...
