A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is at most 3.1 strokes. State Ho and H, in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. O A. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer "Ho: o+ 3.1." not 3.1 strokes." The null hypothesis is expressed symbolically as, O B. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer i "Ho: 023.1." at least 3.1 strokes." The null hypothesis is expressed symbolically as, at most 3.1 strokes." The null hypothesis is expressed symbolically as, Oc. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer "Họ: os3.1." O D. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer "Ho: o = 3.1. equal to 3.1 strokes." The null hypothesis is expressed symbolically as, State the alternative hypothesis in words and in symbols. Choose the correct answer below. OA. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is less than 3.1 strokes." The alternative hypothesis is expressed symbolically as, "H: o<3.1." O B. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not 3.1 strokes." The alternative hypothesis is expressed symbolically as, "H: o# 3.1." OC. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is 3.1 strokes." The alternative hypothesis is expressed symbolically as, "H,: o = 3.1." O D. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is more than 3.1 strokes." The alternative hypothesis is expressed symbolically as, "H: o> 3.1." The hypothesis test is V because the contains

A baseball team claims that the mean length of its games is 2.4 hours. State H0 and Ha in words and in symbols. Then determine whether the hypothesis test for this claim is​ left-tailed, right-tailed, or​ two-tailed. Explain your reasoning.       State the null hypothesis in words and in symbols. Choose the correct answer below.     A. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is at most 2.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≤2.4​."   B. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is more than 2.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≠2.4​."   C. The null hypothesis expressed in words​ is, "the mean length of a baseball​ team's games is at least 2.4 ​hours." The null hypothesis is expressed symbolically​ as, ​"H0​: μ≥2.4​."   D. The null hypothesis expressed in words​ is, "the mean length of a baseball​…

A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is less than 1.5 strokes. State H, and H, in words and in symbols. Then determine whether the hypothesis test for this claim is left-tailed, right-tailed, or two-tailed. Explain your reasoning. State the null hypothesis in words and in symbols. Choose the correct answer below. O A. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at least 1.5 strokes." The null hypothesis is expressed symbolically as, "Ho: 02 1.5." O B. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at most 1.5 strokes." The null hypothesis is expressed symbolically as, "Ho:os1.5." O C. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is less than 1.5 strokes." The null hypothesis is expressed symbolically as, "Ho: o1.5." The hypothesis test is because the V contains

A null and alternative hypothesis are given. Determine whether the hypothesis test is left-tailed, right-tailed, or two-tailed. Ho: Ha: p = 0.7 p = 0.7 What type of test is being conducted in this problem? A. Right-tailed test B. Two-tailed test C. Left-tailed test 20
