2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

Question

### Cholesterol Level and Age Study

#### Cholesterol Level Overview
Cholesterol level tends to increase with age in both women and men. A medical researcher is investigating whether the average cholesterol level for women over 60 years is lower than that of men over 60 years. The researcher uses statistical inference by taking random samples: 110 women and 120 men who are over 60 years old. The summary statistics from these samples are as follows:

| Population/Group | Gender | Mean Cholesterol Level (mg/dL) | Standard Deviation (mg/dL) |
|------------------|--------|-------------------------------|----------------------------|
| 1 | Women | 196.9 | 39.8 |
| 2 | Men | 205.4 | 41.9 |

#### Analysis Method
The medical researcher uses an appropriate hypothesis test to compare the cholesterol levels.

#### Hypothesis Test Inquiry
What is the test statistic for this hypothesis test? Provide your answer to 4 decimal places.
