A random sample of 100 young women revealed 20 liked the MyPrecious fragrance well enough to purchase it. Similarly, a sample of 200 older women revealed 100 liked the fragrance too, well enough to make a purchase. Use a 0.05 level of significance. Which of the following statements is/are true? I. The computed value of the test statistic is -3.4582 II. There is sufficient evidence to reject Ho and conclude in favor of Ha P - P #G
