Do these results suggest that a) State the appropriate null and alternative hypotheses. Fill in the correct answers below. The appropriate null and alternative hypotheses are Hg: versus H, b) Verify that the requirements to perform the test using the t-distribution are satisfied. Check all that apply. O A. The students were randomly sampled. O B. The sample size is larger than 30. O C. The students' test scores were independent of one another. O D.
