A golfer would like to test the hypothesis that the variance of his golf score equals 10.0. a random sample of 28 rounds of golf
had a sample standard deviation of 3.5. what is the number of degrees of freedom for this hypothesisâ test?
1 answer:
It depends on which statistic test we wish to perform, the formula to find a degree of freedom could be different.
for Normal Distribution test, we do not need to find a degree of freedom
for T-test and Chi-Square test, we do n - 1 to find the degree of freedom, where 'n' is the sample size.
if we have two different sample size, then the degree of freedom is given by (n₁ + n₂) - 2
We are given only one sample size, n = 28, hence the degree of freedom is 28 - 1 = 27

Complimentary means they add up to 90
x is the angle we're looking for
x + 89 = 90
Subtract 81
x = 90 - 89
x = 1
A is the correct answer.
