Determine whether a normal sampling distribution can be used for the following sample statistics. If it can be used, test the claim about the difference between two population proportions p1 and p2
at the level of significance α. Assume that the samples are random and independent. Claim: p1≠p2, α=0.01

Sample Statistics:

x1=36,

n1=75,

x2=38,

n2=65

Determine whether a normal sampling distribution can be used.

The samples are random and independent. A normal sampling distribution

cannot

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.
