A researcher believes that the percentage of people who exercise in California is greater than the national exercise rate. The national exercise rate is 20%. The researcher gathers a random sample of 120 individuals who live in California and finds that the number who exercise regularly is 31 out of 120. Please use the chi-square test to design a complete hypothesis testing process and get appropriate conclusions. (You need to indicate the value of X2obt and df and X2cv)
a) Answer true or false and explain your answer: If it is important not to reject a true null hypothesis, the hypothesis test should be performed at a small significance level. b) Explain exactly how a paired t-test can be formulated as a one-mean t-test. Please please answer that
