SECTION A: THEORY. 1. A) The amount of time it takes students to complete a Statistics II quiz is uniformly distributed between 30 to 60 minutes. One student is selected at random. Find the following: d. The probability that the student requires at least 45 minutes to complete the quiz. The probability that the student completes the quiz exactly 52 minutes. f. Compute the expected time and the coefficient of variation to complete the quiz.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

Compute the expected time and the coefficient of variation to complete the quiz. B) Using 95% confidence, how large a sample should be taken to obtain a margin of error for the estimation of a population proportion of .065? Assume that the data are not available for developing the planning value for r
