A golf analyst claims that the standard deviation of the 18-hole scores for a go

Question

A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is 3.1 strokes. 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 standard deviation of the 18-hole scores for a golfer is at least 3.1 strokes." The null hypothesis is expressed symbolically as, "H0:3.1."

B.The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is at most 3.1 strokes." The null hypothesis is expressed symbolically as,"H0:3.1."

C. The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is more than more than 3.1 strokes." The null hypothesis is expressed symbolically as, "H0:>3.1."

D.The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is 3.1 strokes." The null hypothesis is expressed symbolically as,"H0:=3.1."

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 less than 3.1 strokes." The alternative hypothesis is expressed symbolically as, "Ha:<3.1."

B. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not equal to 3.1 strokes." The alternative hypothesis is expressed symbolically as,"Ha: 3.1."

C. 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, "Ha:>3.1."

D. 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, "Ha:=3.1."

The hypothesis test is (left-tailed, right tailed or two-tailed) beacuse the (null hypothesis, claim, or alternative hypothesis) conatins (_____)

Explanation / Answer

D.The null hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is 3.1 strokes." The null hypothesis is expressed symbolically as,"H0:=3.1."

B. The alternative hypothesis expressed in words is, "the standard deviation of the 18-hole scores for a golfer is not equal to 3.1 strokes." The alternative hypothesis is expressed symbolically as,"Ha: 3.1."
