Question

The UGA Journalism Department is interested in determining if there is a significant difference in the number of hours, on average per week, that UGA males and UGA female students spend reading any online or printed newspaper. Randomly selected students at UGA were asked how many hours per week they read any online or printed newspaper, their age, and gender. The 95% confidence interval for reading newspapers on _F - _M is (-1.5, 1.1).

1) What would this interval let us conclude?

Because 0 is in this interval, we cannot conclude that there is a difference in newspaper reading, on average, for females and males.Because 0 is in this interval, we can conclude that there is a difference in newspaper reading, on average, for females and males.    Because 0 is not in this interval, we can conclude that there is a difference in newspaper reading, on average, for females and males.Because 0 is not in this interval, we cannot conclude that there is a difference in newspaper reading, on average, for females and males.

2) What was the margin of error for this confidence interval?

3) Say instead we wanted to do a hypothesis test to determine if there is a difference, on average, between the males and females.

(a) What are the hypotheses?

Ho:   F    ---Select---  =  ≠  >  <   M

Ha:   F    ---Select---  =  ≠  >  <   M

(b) Given the p-value of 0.08 , what is the correct conclusion?

Reject H_o. There is evidence to conclude that there is a gender difference in newspaper reading at significance level 0.05.Fail to reject H_o. There is no evidence to conclude that there is a gender difference in newspaper reading at significance level 0.05.    Fail to reject H_o. There is evidence to conclude that there is a gender difference in newspaper reading at significance level 0.05Reject H_o. There is no evidence to conclude that there is a gender difference in newspaper reading at significance level 0.05.

Answer 1

Solution Here Ho MF = My vs Hi-Me & My. D here the confidence interval ies (1.5, 6) here o is in this interval, we can't conclude that there is a difference in newpaper reading on average for females & moles D Mangon of error = coidth 1-615-:3 3) Here Ho - MF = UM vs HMF FMM b) Given P-value = 0.08>0.05 So do not reject Ho Fail to reject Ho, there is no evidence to conclude that there is a gender difference on newspaper er
