Transcribed Image Text:(b)
The average mean protection of COVID-19 disease for vaccine Type A is 80,
while the average mean protection for vaccine Type B is 75. The standard
deviations are 5 and 3 respectively. A random sample of a group of 15 people
in a certain medical study were observed under vaccination for both types of
vaccine. Construct a 90% confidence interval for the difference between the
mean protection of COVID-19 disease for the two types of vaccine, assuming
normal populations with unequal variances.

- A generic drug is being tested to test its efficacy (effectiveness) at reducing blood pressure in patients with hypertension (a.k.a. high blood pressure). In a randomized, double-blind experiment with 200 patients, 100 are given the name-brand drug (control group) and 100 are given a generic version of the drug (treatment group). In the control group, the average reduction in blood pressure is 15.2 mmHG with a standard deviation of 11.5 mmHG. In the treatment group, there is an average reduction of 14.6 mmHG and a standard deviation of 12.5 mmHG. Neither group has any outliers. A researcher claims that this study shows the generic drug is not as effective as the name-brand drug. What would be the reply of a statistician?

- A randomized controlled trial is run to evaluate the effectiveness of a new drug for asthma in children. A total of 250 children are randomized to either the new drug or a placebo (125 per group). The mean age of children assigned to the new drug is 12.4 with a standard deviation of 3.6 years. The mean age of children assigned to the placebo is 13.0 with a standard deviation of 4.0 years. Suppose that there are 63 boys assigned to the new drug group and 58 boys assigned to the placebo group. Is there a statistically significant difference in the proportions of boys assigned to the treatments? Run the appropriate test at a 5% level of significance.arrow_forwardA random sample of 12 chemists from Washington State shows an average salary of $39,420 with a standard deviation of $1659, while a random sample of 26 chemists from New Mexico has an average salary of $30,215 with a standard deviation of $4116.
