Normal Distribution Activity: A total of 82 Grade 11 students of ABC Senior High School took the 60-item test in General Mathematics. The result is normally distributed with the mean of 42 and standard deviation of 6. Construct a bell curve to display the data and answer the following questions. 1. How many students in each score interval? H- 30 - u- 20 H- 20 --a 4+ロ→+ 2a u+ 20 - u+ 30 2. If the passing score is 36, how many students passed the test? How many of them failed? 3. Only Pamela and three of her classmates got the score of 48. How many students got a score higher than them? How many got a score lower than 48?

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.
