In randomized, double-blind clinical trials of a new vaccine, monkeys were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After the second dose, 118 of 704 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 75 of 585 of the subjects in the control group (group 2) experienced drowsiness as a side effect. Does the evidence suggest that a higher proportion of subjects in group 1 experienced drowsiness as a side effect than subjects in group 2 at the a = 0.10 level of significance? Verify the model requirements. Select all that apply. A. The data come from a population that is normally distributed. B. The samples are independent. O C. The sample size is more than 5% of the population size for each sample. O D. The samples are dependent. LE The sample size is less than 5% of the population size for each sample. E n (1-) 2 10 and ng2 (1-P2) 21 2 10 Determine the null and alternative hypotheses. Ho: P1 = P2 1:P1 > P2 Find the test statistic for this hypothesis test. (Round to two decimal places as needed.)

Unitary Method

The word “unitary” comes from the word “unit”, which means a single and complete entity. In this method, we find the value of a unit product from the given number of products, and then we solve for the other number of products.

Units and Measurements

Measurements and comparisons are the foundation of science and engineering. We, therefore, need rules that tell us how things are measured and compared. For these measurements and comparisons, we perform certain experiments, and we will need the experiments to set up the devices.
