When conducting a hypothesis test, what would it mean if the researcher obtains a negative test statistic? The sample is too small. It’s very unlikely the results would have occurred just by chance alone. The sample statistic is smaller than the claimed population parameter. A mistake was made in terms of calculating the test statistic. The sample statistic is larger than the claimed population parameter.
How does hypothesis testing help support the fields that employ the scientific method?
Many consumer groups feel that the U.S. Food and Drug Administration (FDA) drug approval process is too easy and, as a result, too many drugs are approved that are later found to be unsafe. On the other hand, a number of industry lobbyists have pushed for a more lenient approval process so that pharmaceutical companies can get new drugs approved more easily and quickly. The FDA wants to set up a hypothesis test to show that the new drug is safe before approving it by assuming it to be unsafe. Match the followings concepts to their correct interpretations in the context of the question: Null hypothesis Alternative hypothesis Type I error Type II error A. The new drug is unsafe but the FDA concludes that it is…

A teacher believes that the percentage of students at her high school who go on to college is higher than the rate in the general population of high school students. The rate in the general population of high school students is 30%. In the most recent graduating class at her high school, the teacher found that 90 students graduated and that 40 of those went on to college. Please use the chi-square test to design a complete hypothesis testing process and get appropriate conclusions. (You need to indicate the value of X2obt and df and X2cv)
