a. 675.00

b. The sampling distribution is normally distributed because there is a large sample size (>30) so it

it follows the Central Limit Theorem .

Problem -6.

Ho - u=1; (The mean amount of paint is 1 gallon); H1 - u=/=1 (The mean amount of paint is not 1 gallon)

a. Decision Rule states to reject Ho if lZstatl > 2.5758

b. test statistic: Zstat = (xBar - u)/(sd/n) = (.995 - 1) / (.02/sqrt 50) = -1.7678

c. 2.5758

d. .0771

e. lZstatl282; (The mean driving distance is greater than 282 yards); H1 - u1.6766. There is sufficient evidence to suggest that the mean driving distance is not greater

than 282

h. p-value = .0001 2.0017 or p-value 2.0017.There is sufficient to conclude that there is a difference in the means of the average spent

on couples vacationing in Jamaica versus Bermuda

h. p-value = .0001
