Apply the steps in hypothesis testing to test the validity of the claim in each situation below. 1. The average IQ of a certain population is 100 with a standard deviation of 15. A team of scientists wants to test a new medication to see if it has either a positive or negative effect on intelligence, or no effect at all. A random sample of 30 participants who have taking the medication has a mean of 140. Did the medication affect intelligence, test the claim using alpha = 0.05? 2. A simple random sample of 15 people from a certain population has a mean age of 35 with a standard deviation of 20. Can we conclude that the mean age of the population is younger than 35? Let alpha = .05
