In 1997, a survey of 880 households showed that 168 of them use e-mail. Use those sample results to test the claim that more than 15% of households use e-mail. Use a 0.05 significance level. Use this information to answer the following questions. Use a scrap piece of paper to write out the steps to solve...hypothesis testing problems are very difficult to work in your head!! Use your calculator to perform a 1-PropZTest since this problem is testing proportions. Note: NO sample mean nor standard deviation is given in the problem, therefore, proportion testing is implied a. Which of the following is the hypothesis test to be conducted? О А. Но: р3D0.15 H1: p> 0.15 В. Но: р3D0.15 H1: p<0.15 О с. Но: р> 0.15 H1: p 0.15 D. Ho p 0.15 H1: p 0.15 ОЕ. Но: р#0.15 HI p 0.15 OF. Но: р<0.15 H1: p 0.15 b. What is the test statistic? Z= (Round the final answer to two decimal places as needed.) c. What is the P-value? P-value= (Round to four decimal places as needed.) d. What is the conclusion?
