Question

Transcribed Image Text:It is commonly held that around 15.7% of American college students regularly use marijuana. A certain school
wants to determine if its percentage is higher than the national average. They take a random sample of 100
students and want to use those data to test a hypothesis.
What conditions, if any, are not met to be able to run a hypothesis test?
O Sample Size Condition
O 10% Condition
O Randomization Condition
O None of these; all conditions for a hypothesis test are met

- In hypothesis testing, if the test statistic is negative, this means the sample statistic is larger than the claimed population parameter. O we call the initial claim being tested about the population an alternative hypothesis. the "P" in P-value stands for "personal."
