# C02 - Random Variables

When attempting to create a histogram of the above data, an error stating "'height' must be expressed as a vector or matrix" occurs. I am unsure if this step is required for the assignment, but the command used in the example does not seem to function.

The data can be approximated as normal distribution since p > 0.21.

# Problem From The Book

GRE scores, Part I. Sophia who took the Graduate Record Examination (GRE) scored 160 on the Verbal Reasoning section and 157 on the Quantitative Reasoning section. The mean score for Verbal Reasoning section for all test takers was 151 with a standard deviation of 7, and the mean score for the Quantitative Reasoning was 153 with a standard deviation of 7.67. Suppose that both distributions are nearly normal.
