Question

1. the ages of a group of patients being treated at one hospital for osteoporosis are summarized in the frequency histogram on the right. state whether the distribution is (roughly) symmetric, right skewed, or left skewed. a) left skewed b) symmetric c) right skewed

Explanation:

Step1: Recall the definition of skewness

In a right - skewed distribution, the tail is on the right side. In a left - skewed distribution, the tail is on the left side. A symmetric distribution has a balanced shape on both sides.

Step2: Analyze the histogram

Looking at the histogram, the tail of the distribution is on the left side. The majority of the data (higher frequencies) is on the right side (higher age values), and the frequency decreases as we move to the left (lower age values).

Answer:

a) Left - skewed
