Determine the null and alternative hypotheses. Choose the correct answer below.
Ο Α. Ho: μ = 200
Ha: u< 200
О В. Н: и#200
Ha: μ 200
Ос. Но: и- 200
Ha: H#200
O E. Ho: µ<200
Ha: μ2 200
O F. Ho: u> 200
Ο D. Ho: μ = 200
Ha: u> 200
Ha: us 200
The test statistic is
(Type an integer or a decimal. Do not round.)
The p-value is:
(Type an integer or a decimal. Do not round.)
Interpret the results of the test.
Since the p-value is
V the significance level,
Ho. There is
evidence to conclude that the mean cholesterol level is
200 mg/dL at a significance level of 0.05.
