Question

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

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

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

α=0.10,

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

37	27	31	32	33	39	26	27	30
25	32	34	33	26	28	30	30	22

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

P=enter your response here

(Round to three decimal places as needed.)

Can you explain what needs to be put into the calculator to figure out this problem??

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
