Only receiving responses from half of the people in the sample.D. Using sample random sample of students at a university to estimate the proportion of people whothink the legal drinking age should be lowered18. Take the formula Z = (X-u)/a, where u is the mean of the population, X is the value of the element,Z is the z-score and o is the standard deviation. What does this formula calculate? *A. Confidence interval.B. Standard score.C. Variance.D. Standard error of the mean.19. Suppose that in an adult population the proportion of people who are both overweight and sufferhypertension is 0.09; the proportion of people who are not overweight but suffer hypertension is0.11; the proportion of people who are overweight but do not suffer hypertension is 0.02; and theproportion of people who are neither overweight nor suffer hypertension is 0.78.

A die is called "balanced" or "fair" if each side is equally likely to land on top. Assign a probabilityto each outcome in the sample space for the experiment that consists of tossing a single fair die. Findthe probabilities of the events: "an even number is rolled" *А. 1/2В. 1С. 2D. 321. Compare the scores: a score of 220 on a test with a mean of 200 and a standard deviation of 21and a score of 90 on a test with a mean of 80 and a standard deviation of 8*A. A score of 90 with a mean of 80 and a standard deviation of 8 is betterB. A score of 220 with a mean of 200 and a standard deviation of 21 is better.C.
