The cost of a daily newspaper varies from city to city. However, the variation among prices remains steady with a standard deviation of 20￠. A study was done to test the claim that the mean cost of a daily newspaper is $1.00. Twelve costs yield a mean cost of 95￠ with a standard deviation of 18￠. Do the data support the claim at the 1% level? Complete the blanks within the hypothesis testing procedures as follows:

Statements of null and alternative hypotheses:
H0: μ ___ $1.00
Ha: μ ___ $1.00

(where blanks 1 and 2 require appropriate symbol, such as “equal”, “not equal”, “less than” or “more than”)

Sample z score = (3 decimal places)

Critical z score(s) = (2 decimal places with indication of direction(s))

p-value = (4 decimal places)

Decision: null hypothesis (enter either “Reject” or “Do not reject”)
