A golf analyst claims that the standard deviation of the 18-hole scores for a golfer is less than 2.9 strokes. 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 standard deviation of the 18-hole scores for a golfer is at least 2.9 strokes." The null hypothesis is expressed symbolically as, "H0: σ≥2.9." B. 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, "H0: σ≠2.9." C. 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, "H0: σ<2.9." D. 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, "H0: σ≤2.9." State the alternative hypothesis in words and in symbols. Choose the correct answer below. The hypothesis test is___________ ▼ right-tailed left-tailed two-tailed because the__________ ▼ alternative hypothesis claim null hypothesis contains__________ greater than or equals .≥. greater than .>. equals .=. not equals .≠. less than or equals .≤.

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 2.9 strokes." The null hypothesis is expressed symbolically as, "H0: σ≥2.9."
B.
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, "H0: σ≠2.9."
C.
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, "H0: σ<2.9."
D.
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, "H0: σ≤2.9."
State the alternative hypothesis in words and in symbols. Choose the correct answer below.
The hypothesis test is___________
▼
right-tailed
left-tailed
two-tailed
because the__________
