Multiple Choice

Suppose Apple would like to test the hypothesis that the standard deviation for the web-browsing battery life of the iPad is different from 3.0 hours. The following data represents the battery life, in hours, experienced by a random sample of six users: 10 14 12 16 10 6. A 95% confidence interval for variance of the battery life is given by [4.78, 73.79]. What is the decision and conclusion?

• A) Reject the null hypothesis, we can conclude the standard deviation is different from 3 hours.
• B) Reject the null hypothesis, we cannot conclude the standard deviation is different from 3 hours.
• C) Do not reject the null hypothesis, we can conclude the standard deviation is different from 3 hours.
• D) Do not reject the null hypothesis, we cannot conclude the standard deviation is different from 3 hours.
