A golf analyst claims that the standard deviation of the 18h
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 (_____)
Solution
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.\"
