Find the p-value based on a standard normal distribution for each of the following standardized test statistics.

(a) z=0.75 for a right tail test for a difference in two proportions

Round your answer to two decimal places.

(b) z=-2.29 for a left tail test for a difference in two means

Round your answer to three decimal places.

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.
