(a) identify the claim and state H(o)and H(a)

(b) use technology to find the P-value,

(d) interpret the decision in the context of the original claim. Assume the population is normally distributed.

30. Class Size 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 at the left. At α = 0.05, can you support the
university's claim?

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.
