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.

**Exercises**

**A.** The UM Ross School of Business has 300 students who graduate with a bachelor's degree each year. A random sample of students was selected, and their GMAT scores were reported. Whether or not they were seeking admission to a graduate business school in the next year was recorded.

Here is additional information that you may need to answer the questions.

- Total GMAT Scores are normally distributed, ranging from 200 to 800. The current average combined GMAT score is 560, with a standard deviation of 100.

- Among the Ross sample, the average GMAT score was 580, with a standard deviation of 85.

- In the population of students graduating from Ross, 72% seek admission to a graduate business school in the next year.

Make sure to use the new concepts in this module. This exercise is different from the previous standardized test exercises. It is using sample data.

1. There is a _______ percent chance that a simple random sample of 10 applicants will provide an estimate of the population mean GMAT score that is within +/-10 of the actual population mean.

2. There is a _______ percent chance that a simple random sample of 30 applicants will provide an estimate of the population mean GMAT score that is within +/-10 of the actual population mean.

- There is a _______ percent chance that the sample mean will be higher than 600.
- There is a _______ percent chance that the sample mean will be between 580 and 620.
- There is a _______ percent chance that the sample mean will be at least 530.

3. There is a _______ percent chance that a simple random sample of 100 applicants will provide an estimate of the population mean GMAT score that is within +/-10 of the actual population mean.

4. There is a _______ percent chance that a simple random sample of 100 applicants will provide an estimate of the population mean GMAT score that is within +/-20 of the actual population mean.

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOS) of major corporations. He believes that the mean systolic blood pressure, H, of CEOS of major corporations is less than 136 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 128 mm Hg and the standard deviation of the sample to be 16 mm Hg.

A study was conducted to examine how anxiety (measured on a metric scale) varies for people from different age groups (<18 years, 19 - 29 years, 30 - 39 years, 40+ years). It was hypothesised that people <18 years old would have the least anxiety of the four age groups. It was also hypothesised that people 40+ years old would have more anxiety than people 19-29 years old. Which of the following would be an appropriate statistical test to conduct, which addresses these hypotheses?

A researcher studying stress is interested in the blood pressure measurements of chief executive officers (CEOs) of major corporations. He has good reason to believe that the mean systolic blood pressure, μ, of CEOs of major corporations is different from 132 mm Hg, which is the value reported in a possibly outdated journal article. He plans to perform a statistical test. He measures the systolic blood pressures of a random sample of CEOs of major corporations and finds the mean of the sample to be 124 mm Hg and the standard deviation of the sample to be 20 mm Hg. Based on this information, complete the parts below. Suppose the true mean systolic blood pressure of CEOs of major corporations is 132 mm Hg. Fill in the four blanks to describe a Type I error. 1.
