For Exercises 7 and 8: (a) state the decision rule, (b) compute the poc population variance, (c) compute the test statistic, (d) state your decision about the null hypothesis, and (e) estimate the p-value. 7. The null and alternate hypotheses are: Hoi Hi =H2 HiH, #Hz A random sample of 10 observations from one population revealed a sample mea of 23 and a sample standard deviation of 4. A random sample of 8 observations from another population revealed a sample mean of 26 and a sample standard devlation of 5. At the .05 significance level, is there a difference between the por ulation means?

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.
