A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is 1.5 strokes. State Ho 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 alternative hypothesis in words and in symbols. Choose the correct answer below.
A. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is more than 1.5 strokes." The alternative
hypothesis is expressed symbolically as, "Ha: sigma > 1.5."
B. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is less than 1.5 strokes." The alternative
hypothesis is expressed symbolically as, "H0: sigma < 1>
C. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is 1.5 strokes." The alternative hypothesis is
expressed symbolically as, "Ha: sigma < 1>
D. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not equal to 1.5 strokes." The alternative
hypothesis is expressed symbolically as, "Ha: != 1.5."
