Question

For a population of normally distributed scores, μ = 120 and σ = 10, approximately what would be the 95% confidence interval of the population mean based upon a random sample of 16 scores with a mean of 110?

105.24 to 106.2

105.1 to 114.9

109.7 to 120.3

144.2 to 159.8

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.
