You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than

3232

students. You want to test this claim. You randomly select

1818

classes taught by full-time faculty and determine the class size of each. The results are shown in the table below. At

alphaαequals=0.010.01,

can you support the university's claim? Complete parts (a) through (d) below. Assume the population is normally distributed.

3838	3131	2626	3535	3232	4040	2525	2323	2828
2727	3333	3838	3434	2828	2626	3333	2828	2727

(a) Write the claim mathematically and identify

Upper H 0H0

and

Upper H Subscript aHa.

Which of the following correctly states

Upper H 0H0

and

Upper H Subscript aHa?

Upper H 0H0:

muμequals=3232

Upper H Subscript aHa:

muμnot equals≠3232

Upper H 0H0:

muμless than<>

Upper H Subscript aHa:

muμgreater than or equals≥3232

Upper H 0H0:

muμless than or equals≤3232

Upper H Subscript aHa:

muμgreater than>3232

Upper H 0H0:

muμgreater than>3232

Upper H Subscript aHa:

muμless than or equals≤3232

Upper H 0H0:

muμequals=3232

Upper H Subscript aHa:

muμless than<>

Upper H 0H0:

muμgreater than or equals≥3232

Upper H Subscript aHa:

muμless than<>

Your answer is correct.

(b) Use technology to find the P-value.

Pequals=nothing

(Round to three decimal places as needed.)
