Question

9.18 Technology and the Internet Many limousines now offer the latest in high-tech gadgets. DVD players, satellite radio, and wireless Internet connections are some of the high-priced accessories. Suppose Boston Coach will install wireless Internet in all of its vehicles if more than 75% of all clients desire this service. A random sample of clients will be selected, and the resulting information will be used to test the relevant hypothesis. Let p represent the proportion of all clients who would like wireless Internet in a limousine. State the null and alternative hypotheses in terms of p

Answer 1

`H_(0)`: The proportion of clients who would like wireless Internet in a limousine is p

`H_(a)`: The proportion of clients who would like wireless Internet in a limousine is more than p

Explanation:

Null hypothesis will assume the proportion of clients who would like wireless Internet in a limousine is p and alternate hypothesis assume it is more than p.

Next step would be to calculate the sample mean and its corresponding statistic and p-value (not the proportion p above) assuming the conditions in null hypothesis.

If the p-value is small enough in the given confidence level then null hypothesis will be rejected in favor of alternate hypothesis.
