Determine if the following statement is true or false. If you believe that the statement is false, briefly explain why you think it is false. Small values of x² imply that the null hypothesis in a chi-squared test is true. Choose the correct answer below. A. The statement is true. B. The statement is false because hypothesis tests do not prove the truth of the null hypothesis. C. The statement is false because the value of x² is not considered when determining whether the null hypothesis is true. D. The statement is false because large values of x² imply that the null hypothesis is true.

At a magic shop, the salesperson shows you a coin that he says will land on heads more than 70% of the times it is flipped. In an attempt to convince you he's correct, the salesperson asks you to try the coin yourself. You flip the coin 65 times. (Consider this a random sample of coin flips.) The coin lands on heads 49 of those times. Complete the parts below to perform a hypothesis test to see if there is enough evidence, at the 0.10 level of significance, to support the salesperson's claim that the proportion, p, of all times the coin lands on heads is more than 70%. (a) State the null hypothesis H, and the alternative hypothesis H, that you would use for the test. Ho H: 0 D=D (b) For your hypothesis test, you will use a Z-test. Find the values of np andn (1-p) to confirm that a Z-test can be used. (One standard is that np 2 10 and n(1-p) > 10 under the assumption that the null hypothesis is true.) Here n is the sample size and p is the population proportion you are testing.
