Suppose a professional golfing association requires that the standard deviation of the diameter of a golf ball be less than 0.005 inch. Determine whether these randomly selected golf balls conform to this requirement at the α=0.01 level of significance. Assume that the population is normally distributed. LOADING...

What are the correct hypotheses for this test?

H0:

▼

▼

less than

not equals≠

nothing

versus

H1:

▼

(Type integers or decimals. Do not round.)

Find the sample standard deviation.

s=nothing

(Round to five decimal places as needed.)

Use s to calculate the value of the test statistic.

χ20=nothing

(Round to two decimal places as needed.)

Identify the critical value(s) for this test.

The critical value is

nothing.

(Round to three decimal places as needed. Use a comma to separate answers as needed.)

What is the correct conclusion at the

α=0.01

level of significance?

Since the test statistic is

▼

less

greater

than the critical value,

▼

reject

do not reject

the null hypothesis. There

▼

is not

sufficient evidence to conclude that these golf balls conform to the requirement at the

0.01

level of significance.
