A sociologist is studying the age ofthe population in Blue Valley. Ten years ago, the population was such that 19% were under 20 years old, 12% were in the 20- to 35-year-old bracket. 34% were between 35 and 50, 24% were between 51 and 65, and 11% were over 65. A study done this year used a random sample of 210 residents. This sample is given below. At the 0.01 level of signicance. has the age distribution of the population of Blue Valley changed? Under 20 20 - 35 36 - 50 51 - 65 Over 65 28 25 65 57 25 (i) Give the value of the level of signicance. l State the null and alternate hypotheses. L) Hg: Ages under 20 years old, 20 to 35yearold, between 36 and 50. between 51 and 65, and over 65 are independent. H1: Ages under 20 years old, 20 to 35yearoldr between 36 and 50, between 51 and 55, and over 65 are not independent. '\\_,-' Ho: The distributions for the population 10 years ago and the population today are the same. H1: The distributions for the population 10 years ago and the population today are different. '3.._J Hg: The population 10 years ago and the population today are independent. H1: The population 10 years ago and the population today are not independent. '\\_,' Ho: Time ten years ago and today are independent H1: Time ten years ago and today are not independent. (ii) Find the sample test statistic. (Round your answer to two decimal places.)
