Assume that two fruit flies are randomly selected with replacement.3 malesBilly, Carlos, and Denny1 femaleEmilya.After listing the possible samples and finding the proportion of in each sample, use a table to describe the sampling distribution of the proportion of .
b.Find the mean of the sampling distribution.(Round to two decimal places as needed.)
c.Is the mean of the sampling distribution [from part (b)] equal to the population proportion of ? If so, does the mean of the sampling distribution of proportions always equal the population proportion?
malesID: 6.2.38-TAssume that a randomly selected subject is given a bone density test. Bone density test scores are normally distributed with a mean of 0 and a standard deviation of 1. Draw a graph and find , the percentile. This is the bone density score separating the bottom from the top P1818th18%82%.Which graph represents ?
