9. Circle True if the statement is correct and False if it is incorrect. a. True - False Given H: p + 0.6, z = 0.78, then P-value = 2 P(z < 0.78). b. True - False Given H1: o < 0.629, n = 19, and a = 0.025 then CV = 31.526. c. True - False Given H;: µ < 2.8, n = 19, and a = 0.05 then CV = 1.734. d. True - False Ifn = 696 and p = 30%, then x = 209. If someone claims that the mean is over 523 and the test result e. True - False rejects Ho, then there is not sufficient evidence to support the claim that the mean is greater than 523. If the claim says that the mean IQ score of movie patrons is different f. True - False from 100 and we reject Ho then we have enough evidence to reject the claim. g. True - False If H;: o < 14.7 and we reject Ho then there is not sufficient evidence to support the claim that the standard deviation is less than 14.7. h. True - False Ifn = 677 and x = 172, then p= 0.26.
