A health agency suggested that a healthy total cholesterol measurement should be 200 mg/dL or less. Records from 50 randomly and independently selected people from a study conducted by the agency showed the results in the technology output given below. Test the hypothesis that the mean cholesterol level is more than 200 using a significance level of 0.05. Assume that conditions are met. One-Sample T Test of H = 200 vs > 200 N Mean StDev SE Mean T P 50 208.05 39.39 5.57 1.45 0.077 Determine the null and alternative hypotheses. Choose the correct answer below. O A. Ho: H > 200 O B. Ho: H = 200 O C. Ho: H = 200 Ha: HS 200 Ha: H 200 Ha: H = 200 The test statistic is. (Type an integer or decimal rounded to two decimal places as needed.) The p-value is. Type an integer or decimal rounded to three decimal places as needed.) Interpret the results of the test. Since the p-value is the significance level, Ho. There is evidence to conclude that the mean cholesterol level is more than 200 mg/dL at a significance level of 0.05
