Question

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

H0: mu = 54.2

Ha: mu > 54.2

You believe the population is normally distributed and you know the population standard deviation is 14.7. You obtain a sample mean of 58.3 for a sample of size n = 32

Required:

Compute the test statistic for this sample?

Test statistic = (Round to 1 decimal)....

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.
