The number of grants of carbohydrates contained 1-ounce servings of randomely selected chocolate and non-chocolate candy is listed below. Is there evidence to conclude that there is a difference between in mean carbohydrates between chocolate and non-chocolate candies? Use the unequal variance T-test and significant level =.05. Assume carbohydrates per serving is normally distributed for both types of candy. Chocolate:29,25,17,36,41,25,32,29,38,34,24,27,29 Non-chocolate: 41,41,37, 29,30,38,39,18,29,55,29 a.) State the null and alternative hypotheses. b.) Identify test statistic and p-value. c.) Make a decision, reject Ho or not? D.) Summarize the results in a sentence.

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.
