Question

A data set about speed dating includes "like" ratings of male dates made by the female dates. The summary statistics are

n=190,

x=7.81,

s=1.93.

Use a

0.05

significance level to test the claim that the population mean of such ratings is less than

8.00.

Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the final conclusion that addresses the original claim.

What are the null and alternative hypotheses?

H0:

μ=8.00

H1:

μ>8.00

H0:

μ=8.00

H1:

μ≠8.00

H0:

μ<8.00

H1:

μ>8.00

H0:

μ=8.00

H1:

μ<8.00

Determine the test statistic.

(Round to two decimal places as needed.)

Determine the P-value.

nothing

(Round to three decimal places as needed.)

State the final conclusion that addresses the original claim.
