Information: Flu season comes every year and it is time to look at who in our community is most likely going to get us sick. Using a representative sample of the general population in the United States, we have constructed a table that shows flu vaccination status by age group. People were categorized as vaccinated for the 2015 flu season if they received influenza vaccine between September and November of 2014. Since we are confident in the representativeness of our...

8.) The U.S. Army requires women’s heights to be between 57 in and 79 in. a.) Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join the Army because they are too short or too tall? b.) If the U.S. Army changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements? Note: Women’s heights are normally distributed with...

Instructions: Write probabilities to four decimal places (percentages to two decimal places). Draw bell curves to illustrate each desired areas. Use the correct probability notation (e.g. P(X >12.5) = P(z > 1.2) …. Use the Standard Normal Distribution Table to answer Questions 1 & 8). 1. The total blood cholesterol levels in a certain Mediterranean population are found to be normally distributed with a mean of 160 milligrams/deciliter (mg/dL) and a standard deviation of 50 mg/dL.

Q: A 95% confidence interval for the mean is (102, 106). If we test Ho: ? = 100 vs. H1: ? ? 100, the p-value will be: (A) larger than 0.05 (B) smaller than 0.05 (C) larger than 0.01 (D) smaller than 0.01 Q: Suppose you want to conduct a t-test using ? = 0.05. You take a random sample of size 30 and obtain the sample mean and sample standard deviation. As a result, you fail to reject the...

Let X denote the courtship time for a randomly selected female-male pair of mating scorpion flies (time from the beginning of interaction until mating). Suppose the mean value of X is 120 min and the standard deviation of X is 110 min (suggested by data in the article "Should I Stay or Should I Go? Condition- and Status-Dependent Courtship Decisions in the Scorpion Fly Panorpa Cognate"†). (a) Is it plausible that X is normally distributed? No, courtship time cannot plausibly...
