Question

In a recent court case it was found that during a period of 11 years 851 people were selected for grand jury duty and 39% of them were from the same ethnicity. Among the people eligible for grand jury duty, 79.9% were of this ethnicity. Use a 0.05 significance level to test the claim that the selection process is biased against allowing this ethnicity to sit on the grand jury.

1.Identify the test statistic

2. Identify the P-value

3. What is the conclusion about the null hypothesis

4. Find the final conclusion that addresses the original claim. Use the P-value method and the normal distribution as an approximation to the binomial distribution.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
