Answer 1

Question

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.

The condition when it is appropriate to use one-sample Z-test.

Expert Solution & Answer

Answer to Problem 1TP

The Z-test is used when the sample size is large (>30) and the population standard deviation or variance is known. One sample Z-test can be used for comparing one sample mean with population mean.

Explanation of Solution

The central limit theorem states that if the sample size tends to be larger, then the test statistics tends to be a normal distribution. For large sample size and known population variance, one sample Z-test is appropriate to use. One sample Z-test is used for comparing one sample mean with population mean.
