Use normalcdf command to answer the questions below. A college’s data about incoming freshman indicates that the mean of their high school GPAs was 3.2 with a standard deviation of 0.65. Incoming freshman arerandomly assigned to writing seminars in groups of 25. a) Find the mean and standard deviation of the sampling distribution and describe the sampling distribution using the notation ?(?, ?).b) What is the probability of a group having an average high school GPA above 3.5?c) What is the probability of a group having an average high school GPA below 3.0?
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.
