Two types of medicine were used on 5 and 7 patients for reducing their weights in Jerry's 'slim-beauty' health club. Medicine A was allopathic and medicine B was Herbal. The weight after using the medicine for 6 months was as follows: 10 12 13 11 14 8| 9| 12 | 14| 15| 10 9 Medicine A Medicine B Test the hypothesis if there are significant differences in medicine B and medicine A by using 0.001 of significance level. Assume that the variances of population are unknown but equal.

What type of error could you have made in your decision?There are many ways to measure the reading ability of children. Research designed toimprove reading performance is dependent on good measures of the outcome. Onefrequently used test is the DRP, or Degree of Reading Power. A researcher suspects that themean score µ of all third- graders in Henrico County Schools is different from the nationalmean, which is 32.

- Q3.3 Normal, but why? A meal package for use at the space station is to be prepared by combining three separate components: protein, fruit/vegetable, and grains. Each of the components is to be randomly selected. Summary values for the caloric content for each of the components are given in the table. Component Protein (P) Fruit/vegetable (F) Grain (G) Mean (calories) 120 55 84 Stdv (calories) 6.4 Save Answer 1.0 3.6 Assume that the distributions of caloric content for each of the components are approximately normally distributed. Since the meal package consists of protein, fruit/vegetable, and grains, the total caloric content of a meal package is the random variable T, where T = P + F + G. Briefly explain why it is appropriate to say that T is approximately normally distributed. Q3.4 Probability Less than 275 Calories On your own piece of paper find the approximate probability that a randomly selected meal package will have less than 269 calories?
