Hello, could you please help me solve these problems? And please explain everything that I should know? Explain everything you think the reader should know. (without using excel) Student 1 Student 2 Student 3 Student 4 Student 5 Student 6 Student 7 Student 8 Student 9 Height (inches) 63 67 68 68 69 70 71 74 75 Weight (lbs) 140 160 140 149 165 125 235 260 190 ∝=0.05 Construct a confidence interval to estimate the mean weight.
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.
