Mr Stat, our local statistics teacher conducted a study of his students. He recorded the time a sample of 45 students spent studying per week and found they had a distribution which was right-skewed with a mean of 8.4 hours and a standard deviation of 2.7 hours. Part A - Find the sampling distribution of X? H= and O = If not exact, please round to 4 decimal places. Part B- Find the probability the mean time spent studying per week is between 8 and 9 hours.

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.
