Complete parts (a) through (d) below. (a) Write the claim mathematically and identify Ho and Ha Choose the correct answer below. O A. Ho: H 1100 O B. Ho: Ha: 110 Ha s 110 O D. Ho: 2110 O C. Ho: 110 H.: 110 Ha 1100 (b) Calculate the standardized test statistic. t. Round to two decimal places as needed. Use technology to calculate the Pvalue. (Round to three decimal places as needed.) (c) Decide whether to reject or fail to reject the null hypothesis. O A Fail to reject Ho because the P-value is less than the significance level, 0.05. O B. Reject Ho because the P-value is less than the significance level. 005. Click to select your answer(s). O GQ
