Question

4). We have price-per-can information for independent
samples of two soup varieties. Assume the
populations of prices each follow normal
distributions. Find the 99% CI for the difference
between the two population means. Use df = 20,
if needed. Then use the CI to conduct a NATDRC
test of the claim of no difference in the population
means.

soup #1: n = 15, X-bar = 0.73, s = 0.05 (in $)
soup #2: n = 24, X-bar = 0.91, s = 0.03

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.
