Question

Use the normal distribution curve to illustrate your answer.

1. The following simple random sample was selected from a normal distribution: 4, 6, 3, 5, 9, and 3.

a) Construct a 90% confidence interval for the population mean μ.

b) Construct a 95% confidence interval for the population mean μ.

c) Construct a 99% confidence interval for the population mean μ.

d) Assume that the sample mean x and sample standard deviation s remain exactly the same as those you just calculated but that they are based on a sample of n = 25 observations rather than n = 6 observations. Repeat parts a-c. What is the effect of increasing the sample size on the width of the confidence intervals?

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.
