In randomized, double-blind clinical trials of a new vaccine, infants were randomly divided into two groups. Subjects in group 1 received the new vaccine while subjects in group 2 received a control vaccine. After thesecond dose, 115 of 677 subjects in the experimental group (group 1) experienced drowsiness as a side effect. After the second dose, 72 of 558 of the subjects in the control group (group 2) experienced drowsinessas 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 = 0.01 level of significance?Verify the model requirements.

e A researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students made toward completing a bachelor's degree. One aspect of his research vas to determine whether students who first attended community college took longer to attain a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the esults of his study. Complete parts a) through e) below. E Click the icon to view the sample data. OA. The samples are independent. O B. The samples can be reasonably assumed to be random. OC. The population is given to be normally distributed. OD. The sample sizes are large (both greater than or equal to 30). O E.

Logging activity in forests is thought to affect the behavior of black bears. An important measure of animal behavior is the home range, the area used by animals in their daily lives. In a study of black bears in a logged Canadian forest, the spring and early summer home ranges (in square kilometers) of 12 radio-collared female black bears was measured. The results are below. Assume the home range of female black bears in this logged forest is normally distributed. 39.9, 23.5, 42.1, 29.4, 34.4, 40.9, 27.9, 22.3, 13.0, 20.1, 13.3, 8.6 d) Construct and interpret a 95% confidence interval for the mean home range of female black bears in this logged forest. e) The typical home range of females in forests with no logging is 20 square kilometers. Based on the confidence interval above, do you think that the mean home range size of females in this logged forest could be the same as the mean home range size in non-logged forests? Explain.

K Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The aircraft can carry 41 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6,765 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the passengers is greater than 6,765 lb 41 Should the pilot take any action to correct for an overloaded aircraft? Assume that weights of men are normally distributed with a mean of 183.6 lb and a standard deviation of 35.4. The probability is approximately (Round to four decimal places as needed.)
