Question

You wish to test the following (Ha) at a significance level of a=0.05

Ha:u=0.38

Ha:p>0.38

You obtain a sample of size n=716 in which there are 302 successful observations. For this test, you should NOT use the continuity correction, and you should use the normal distribution as an approximation for the binomial of.

What is the test statistic for this sample in three decimal places?

What is the p value for this sample in four decimal places?

The p value is less or greater than a?

This test statistic leads to a decision to, reject the null, accept the null, or fail to reject the null.

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.
