- A pharmaceutical company claims that its new drug reduces systolic blood pressure. The systolic blood pressure (in millimeters of mercury) for nine patients before taking the new drug and 22 hours after taking the drug are shown in the table below. Is there enough evidence to support the company's claim? Let d=(blood pressure before taking new drug)−(blood pressure after taking new drug)d=(blood pressure before taking new drug)−(blood pressure after taking new drug). Use a significance level of α=0.01α=0.01 for the test. Assume that the systolic blood pressure levels are normally distributed for the population of patients both before and after taking the new drug.

- Does training in stress reduction make a difference for student success? 15 students received training (M1= 88, SS1= 400) and 15 students did not (M2= 82, SS2= 440). Test using α = .05 Does training in stress reduction make a difference?The following table shows some data from a study on substance use among 10th graders in the United States and Europe. Smoked Cigarettes Cigarette-Free Totals U.S. x y 12,000 Europe z w 98,000 Total 69,210 110,000 Given that 37,510 more European 10th graders smoked cigarettes than U.S. 10th graders, find the missing data. (x, y, z, w) =The demand for a commodity is given by Q = Bo + B₁P+u, where Q denotes quantity, P denotes price, and u denotes factors other than price that determine demand. Supply for the commodity is given by Q You, where v denotes factors other than price that determine supply. Suppose that u and v both have a mean of zero, have variances o and o2, and are mutually uncorrelated. Solve the two simultaneous equations to show how Q and P depend on u and v.
- Recent studies have shown that adult men suffer from high blood pressure at a lesser rate than do adult women. To test that claim, a research randomly selected 200 of each gender and tested their blood pressure. The results revealed that 49 of the men and 62 of the women suffered from high blood pressure. Can you conclude that the proportion of men with high blood pressure is less than the proportion of women? Use α = 0.05.Apply descriptive measures in the situation below.Your house is in a community where for a certain reason, has many cases of fire. One action made by the government is to put two fire stations far from each other. Your city leader asked you to suggest on what station to contact first in cases of emergency. Since the two stations are of equal distances from your city, you computed for the average response times since the two stations fully operate. Coincidentally, their average response times are equal. Thus, you cannot use this as your basis to report to the purok leader. Your next option is to use the standard deviation, but how will you use it?Josh wants to convince his mother to stop buying single-ply toilet paper. Josh believes that even though Fluffy, a two-ply toilet paper costs more, it will last longer because it is more absorbent. To help substantiate his claim, Josh performed a study. He purchased a random sample of 18 rolls of Fluffy. For each roll, he determined how many squares are needed to completely absorb one-quarter cup of water. Here is a dotplot of the data. The mean of the sample is 24.444 squares with a standard deviation of 2.45 squares. Single-ply toilet paper requires 26 squares to absorb one-quarter cup of water. Josh would like to carry out a test to determine if there is convincing evidence that the mean number of squares of Fluffy that are needed to absorb one-quarter cup of water is fewer than 26 squares. What is the appropriate test statistic and P-value of this test? (A) z = -2.69z=−2.69, PP-value = 0.0036=0.0036 (B) t = -2.69t=−2.69, PP-value = 0.0078=0.0078 (C) t = -2.69t=−2.69, PP-value =…
