Refer to the spinner shown. The spinner is divided into sections with the same area.
a. What is the theoretical probability that the spinner stops on a multiple of 3? Express your first answer as a fraction in simplest form, and
your second answer as a percent.
b. You spin the spinner 30 times. It stops on a multiple of 3 twenty times. What is the experimental probability of stopping on a multiple of
3? Express your first answer as a fraction in simplest form, and round your percent answer to the nearest whole percent.

Arandom sample of n = 25 observations is taken from a n(µ, σ ) population. a 95% confidence interval for µ was calculated to be (42.16, 57.84). the researcher feels that this interval is too wide. you want to reduce the interval to a width at most 12 units. a) for a confidence level of 95%, calculate the smallest sample size needed. b) for a sample size fixed at n = 25, calculate the largest confidence level 100(1 − α)% needed.
