* he sample mean after the drug is M =56 on the task, is this sufficient to reject Ho : : A random sample of n= 16 individuals is selected from a population with u =70 and a treatment is he estimated standard error for the distribution of sample means where H, is true? (HINT: calculate the sample variance and sample standard deviation first!) administered to everyone in the sample. After treatment, the sample mean is M = 76 with SS = 960. What is 5a. Does the treatment have a significant effect using a 2-tailed hypothesis with a = .05? 5. A sample of n = 36 freshmen was selected to participate in a new 4-hour training program to improve study skills. To see how effective the program was it was compared with the rest of the freshmen class, who nad a mean score of u =74. The sample of students in the new program had a mean of M = 79.4 with s = 18. Based on these data, can we conclude that the students in the new program performed significantly better than the rest of the freshmen class? Use a ONE-tailed test with alpha of 05

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.
