researcher investigates whether or not a new cold medication affects mental alertness. A standardized test of alertness is normally distributed with μ = 64 and σ = 8. A random sample of n = 16 students are given the new cold medication and are asked to take the standardized test of alertness. For the sample of n = 16 students, the mean score on the test M = 58. Using the 7 steps of hypothesis testing determine if the new cold medication affects mental alertness (i.e., there is a difference in mental alertness with the cold medication) using α = .05 For this problem 1. State the hypothesis in words 2. State the statistical hypothesis (H1 and Ho) 3. State the α level = 4. State the decision rule and be sure to include the critical value
