, 1. a) Define the null and alternative hypothesis for the following. Also, explain what it would mean to make a
Type I error and explain what it would mean to make a Type II error.
The newspaper in a certain city had a circulation of 15,000 per day in 2010. You believe that the news
more than 15,000 today.
b) Define the null and alternative hypothesis for the following. Also, explain what it would mean to make a
Type I error and explain what it would mean to make a Type II error.
A certain website had 3500 hits per month a year ago. You believe that the number of hits per month is less than that
today.
a. H0: μ =15,000 circulation
H1: μ >15,000 circulation
Type I error: Reject the null hypothesis that the mean of circulations is 15,000 even though it is correct.
Type II error: Do not reject the null hypothesis when the mean of circulations is greater than
15,000circulations.
b. H0:μ =3500 hits
H1:μ <3500 hits
Type I error: Reject the null hypothesis even though the hits per month in a year are at least 3500.
Type II error: Do not reject the null hypothesis when the mean of hits per month is less than 3500.
