A publisher reports that 72% of their readers own a personal computer. A marketing executive wants to test the claim that the percentage is actually over the reported percentage. A random sample of 380 found that 76% of the readers owned a personal computer. Is there sufficient evidence at the 0.01 level to support the executive's claim?

Step 1 of 6: State the null and alternative hypotheses.

Step 2 of 6: Find the value of the test statistic. Round your answer to two decimal places.

Step 3 of 6: Specify if the test is one-tailed or two-tailed.

Step 4 of 6: Determine the decision rule for rejecting the null hypothesis, H0.

Reject H0 if Z>...

Step 5 of 6: Make the decision to reject or fail to reject the null hypothesis.

Step 6 of 6: State the conclusion of the hypothesis test, is there or is there not sufficient evidence to support the claim that the percentage of readers who own a personal computer is over 72%
