For each problem: Step 1: State the null and alternative hypotheses Step 2: Indicate the critical value of the appropriate statistic (and draw a picture of the distribution, showing the alpha/critical region and the critical value of the statistic – you CAN copy this from a table or online calculator) Step 3: Calculate the test statistic/p-value. Step 4: State the decision and conclusion. Do you retain or reject the null hypothesis? And what does that mean in terms of the problem - write a verbal conclusion that relates back to the actual problem. 1. 50 men and 50 women are intercepted at a mall, asked to smell two fragrances (vanilla vs. musk) and then pick the one they like best. The data are shown below. Is gender related to preference for a certain type of fragrance (does it impact which fragrance is preferred?)? Use alpha = .05. Musk Vanilla Men 35 15 Women 20 30
