A random sample of 25 students participated in a contest for the most words memorized in 15 seconds. A researcher wants to know if the mean number of words is equal to 6 or not. Data values were normally distributed and the average number of words memorized for this sample was 5 and the sample standard deviation was 3. Determine whether the necessary assumptions for conducting this hypothesis test are met. A random sample of 25 students participated in a contest for the most words memorized in 15 seconds. A researcher wants to know if the mean number of words is equal to 6 or not. Data values were normally distributed and the average number of words memorized for this sample was 5 and the sample standard deviation was 3. Determine whether the necessary assumptions for conducting this hypothesis test are met. The sample is random, and the sample size is at least 30. Assumptions are met. The sample is not random, so assumptions are not met. The sample is random, but the sample size is < 30. Assumptions are not met. The sample is random, and the sample size is < 30 but the distribution is normal. Assumptions are
