A random sample of n1 = 16 communities in western Kansas gave the following rates of hay fever per 1000 population for people under 25 years of age. Emmi-\"Elm A random sample of n2 = 14 communities in western Kansas gave the following rates of hay fever per 1000 population for people over 50 years old. IE-I-I-I-I-I-Elll Assume that the hay fever rate in each age group has an approximately normal distribution. Using the method outlined in Brase and Brase, do the data indicate that the age group over 50 has a lower rate of hay fever? Use a =0,05. Do you reject or fail to reject the null hypothesis? Are the data statistically significant at the a = 0.05 level of significance
