Arandom sample of n = 25 observations is taken from a n(Β΅, Ο ) population. a 95% confidence interval for Β΅ 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 β Ξ±)% needed.

The probability that a u. s. resident has traveled to canada is 0.18 and to mexico is 0.09. a. if traveling to canada and traveling to mexico are independent events, what is the probability that a randomly-selected person has traveled to both? (page 109 in the book may ) b. it turns out that only 4% of u. s. residents have traveled to both countries. comparing this with your answer to part a, are the events independent? explain why or why not. (page 119 may ) c. using the %βs given, make a venn diagram to display this information. (donβt use your answer to part a.) d. using the conditional probability formula (page 114 in the book) and the %βs given, find the probability that a randomly-selected person has traveled to canada, if we know they have traveled to mexico.
