Need help with this question.

The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a population standard deviation of $0.20. A study was done to test the claim that the mean cost of a daily newspaper is $1.00. Fourteen costs yield a mean cost of $0.95 with a standard deviation of $0.18. Do the data support the claim at the 1% level? Note: If you are using a Student's t-distribution for the problem, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, however.) Part (a) State the null hypothesis. O Ho: H # 1.00 O Ho: H p-value, we reject the null hypothesis. Since a > p-value, we do not reject the null hypothesis. Since a
