D. Reject Ho. There is not sufficient evidence to conclude that a linear relation exists between the rate of return of the index and the rate of returr company stock. Assuming the residuals are normally distributed, construct a 90% confidence interval for the slope of the true least-squares regression line. Lower bound: 0.2367 (Round to four decimal places as needed.) Upper bound: 1.2955 (Round to four decimal places as needed.) What is the mean rate of return for the company stock if the rate of return of the index is 3.15%? . e mean rate of return for the company stock if the rate of return of the index is 3.15% is % pund to three decimal places as needed.)

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.
