Question

A local cable company claims that the proportion of people who have Internet access is less than 63%. To test this claim, a random sample of 800 people is taken and its determined that 478 people have Internet access. The following is the setup for this hypothesis test: H0:p=0.63 Ha:p<0.63 Find the p-value for this hypothesis test for a proportion and round your answer to 3 decimal places.

Answer 1

The p-value for this hypothesis test for a proportion is 0.042. Therefore, we reject the null hypothesis and conclude that the proportion of people with Internet access is less than 63%.

Step-by-step explanation:

The p-value for this hypothesis test for a proportion is 0.042 (rounded to 3 decimal places). Since the p-value is less than the significance level (0.05), we reject the null hypothesis. This means that there is sufficient evidence to conclude that the proportion of people who have Internet access is less than 63%.
