Question

Each of two pesticide brands is applied to 100 containers of fire ants.
Brand1 killed all ants in 65 of 100 containers within two hours, and
Brand 2 killed all ants in 58 of 100 containers within two hours.

a. Is there statistically significant evidence to suggest Brand 1 works better?
Use the hypothesis test based on the normal distribution.
Be sure to check all assumptions, obtain the p-value, and state your conclusion.

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.
