A golf analyst claims that the standard deviation of
the​ 18-hole scores for a golfer is
3.7
strokes. State
H0
and
Ha

test for this claim is​ left-tailed, right-tailed,
or​ two-tailed. Explain your reasoning.

Part 1
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
3.7
​strokes." The null hypothesis is expressed
symbolically​ as,
​"H0​:
σ=3.7​."
B.The null hypothesis expressed in words​ is, "the standard
deviation of the​ 18-hole scores for a golfer
is at least
3.7
​strokes." The null hypothesis is expressed
symbolically​ as,
​"H0​:
σ≥3.7​."
C.The null hypothesis expressed in words​ is, "the standard
deviation of the​ 18-hole scores for a golfer
is at most
3.7
​strokes." The null hypothesis is expressed
symbolically​ as,
​"H0​:
σ≤3.7​."
D.The null hypothesis expressed in words​ is, "the standard
deviation of the​ 18-hole scores for a golfer
is more than
3.7
​strokes." The null hypothesis is expressed
symbolically​ as,
​"H0​:
σ>3.7​."
Part 2
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
3.7
​strokes." The alternative hypothesis is expressed
symbolically​ as,
​"Ha​:
σ<3.7​."
B.The alternative hypothesis expressed in words​ is, "the
standard deviation of the​ 18-hole scores for a golfer
is not equal to
3.7
​strokes." The alternative hypothesis is expressed
symbolically​ as,
​"Ha​:
σ≠3.7​."
C.The alternative hypothesis expressed in words​ is, "the
standard deviation of the​ 18-hole scores for a golfer
is
3.7
​strokes." The alternative hypothesis is expressed
symbolically​ as,
​"Ha​:
σ=3.7​."
D.The alternative hypothesis expressed in words​ is, "the
standard deviation of the​ 18-hole scores for a golfer
is more than
3.7
​strokes." The alternative hypothesis is expressed
symbolically​ as,
​"Ha​:
σ>3.7​."
