4. A used car dealer says the mean price of a 2000 Ford F − 150 Super Cab is more than $16,500. Suppose that we know the population. standard deviation.
H0:
H1:
test statistic:
Homework Answers
here the claim is that the price of the car is more than 16500
Hence below are the null and alternate hypothesis
H0: mu = 16500
Ha: mu > 16500
As here population standard deviation is known, test statistic used for the hypothesis test is z
test statistic : z
