Question

A weatherman stated a null hypothesis that during the month of September, the mean daily temperature of Boston was the same as the mean dailytemperature of New York. His alternative hypothesis was that mean temperatures in these two cities were different. He computed a p-value of 0.275. Using a confidence level of 90%, he should conclude:

a. In September, Boston was colder than New York

b.In September, New York was colder than Boston

c.Reject the null hypothesis

d.Fail to reject the null hypothesis

e.None of the above.

Explanation / Answer

Here the level of significance is 0.10.

The p-value of 0.275 is greater than 0.10. So, fail to reject the null hypothesis at 0.10 level of significance.

d.Fail to reject the null hypothesis
