You receive a brochure from a large university. The brochure indicates that the mean class size for full-time faculty is fewer than 32 students. You want to test this claim. You randomly select 18 classes taught by full-time faculty and determine the class size of each. The results are shown in the table below. At a = 0.10, can you support the university's claim? Complete parts (a) through (d) below.

Ha: µ> 32
О В. Но: и-32
Ha: µ< 32
Ос. Но: и> 32
Hai us 32
Ο D . H : μ2 32
Ha: µ< 32
F. Ho: H< 32
Ha: µ2 32
E. Ho: µ= 32
Ha: µ#32
(b) Use technology to find the P-value.
P =
(Round to three decimal places as needed.)
(c) Decide whether to reject or fail to reject the null hypothesis.
Which of the following is correct?
