Intro to Statistics Final Exam Questions with Complete Solutions Population a collection of persons, things, or objects under study. Sample selecting a portion (or subset) of the larger portion Parameter A numerical characteristic of the whole population that can be estimated by a statistic. Ex: we consider all math classes to be the population, so the average number of points earned per student over all math classes is a parameter. Statistic A number that represents a proper...

MATH 110 MODULE 3 EXAM Module 3 Exam Exam Page 1 Suppose A and B are two events with probabilities: P(Ac )=.40,P(B)=.45,P(A∪B)=.60. Find the following: a) P(A∩B). p(anb) = p(a) + p(b) - p(aub) p(a) = 1 - p(a^c) p(a^c) = 0.40 1 - 0.40 = 0.60 p(a) = 0.60 0.60 + 0.45 - 0.60 = 0.45 P(AnB) = 0.45 b) P(A). p(a) = 1 - p(a^c) p(a^c) = 0.40 1 - 0.40 = 0.60 P(A) = 0.60 c) P(Bc). p(b) = 1 - p(b^c) rearranged to find p(b^c) = 1 - p(b) 1 - 0.45 = 0....

Explain what we mean by a confidence level (exp. 95%) - The percentage of intervals, based on all possible samples of the same size taken from the same population, that contain the parameter. For example, if we construct 100 95% confidence intervals using 100 samples of the same size, approximately 95 of the intervals will contain the true parameter and 5 will not. A point estimate is the value of a _________ that estimates the value of a ____________ - statistic, parameter What are t...
