The mean iq of statistics teachers is greater than 110. write the null and alternative hypotheses. a) h_0: mu lessthanorequalto 110, h_a: mu > 110 a candidate for governor of a particular state claims to be favored by at least half of the voters. state this claim mathematically. write the null and alternative hypotheses. identify which hypothesis is the claim. a) claim: p greaterthanorequalto 0.5; h_0: p greaterthanorequalto 0.5, h_a: p < 0.5; claim is h_0 a researcher claims that 62% of voters favor gun control. determine whether the hypothesis test this claim is left-tailed, right-tailed, or two-tailed. a) two-tailed b) right-tailed c) left-tailed given h_0: mu greaterthanorequalto 23.5 and alpha = 0.05, which level of confidence should you use to test the claim? a) 80% b) 99% c) 90% d) 95% suppose you are using alpha = 0.05 to test the claim that mu > 14 using a p-value. you are given the sample statistics n = 50, x = 14.3, and s = 1.2. find the p-value. a) 0.0384 b) 0.0012 c) 0.0128 d) 0.1321 given h_a: mu > 85 and p = 0.007. do you reject or fail to reject h_0 at the 0.01 level of significance a) fail to reject h_0 b) not sufficient information to decide c) reject h_0 find the critical value for a right-tailed test with alpha = 0.01 and n = 75. a) 2.575 b) 2.33 c) 1.96 d) 1.645
