A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is less than 2.9 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. CD 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 less than 2.9 strokes." The null hypothesis is expressed symbolically as "Ho: 0<2.9." O B. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at most 2.9 strokes." The null hypothesis is expressed symbolically as "Ho: 0829." OC. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not 2.9 strokes." The null hypothesis is expressed symbolically as "Ho: 062.9." OD. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at least 2.9 strokes." The null hypothesis is expressed symbolically as "H: 0229." State the alternative hypothesis in words and in symbols. Choose the correct answer below. O A. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not 2.9 strokes." The alternative hypothesis is expressed symbolically as, "Hg: 0*2.9." O B. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is 2.9 strokes." The alternative hypothesis is expressed symbolically as "Hg: 6=2.9." OC. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is less than 2.9 strokes." The alternative hypothesis is expressed symbolically as, "H,: <2.9." OD. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is more than 2.9 strokes." The alternative hypothesis is expressed symbolically as, "Hg: 0 > 2.9." The hypothesis test is because the contains
