A computer selects a number X from 2 to 10 randomly and uniformly. Round all answers to 4 decimal places where possible. a. What is the distribution of X? Hint: Enter the lowest and highest end points. X~U(___,___) b. Suppose that the computer randomly picks 37 such numbers. What is the distribution of ¯x for this selection of numbers. Hint: Enter the mean and standard deviation. ¯x~N(___,___) c. What is the probability that the average of 37 numbers will be more than 6.7?
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.
A computer selects a number X from 2 to 10 randomly and uniformly. Round all answers to 4 decimal places where possible.
