1. A report in a national magazine estimated that 39 percent of American husbands do not know the color of their wives' eyes. Bill Cornett is a marriage counselor in a clinic in New Orleans. He feels the figure is higher for husbands in the greater New Orleans area. A sample of 264 husbands in this area yielded 111 who did not know the true color of their wives' eyes. a. Conduct a test of significance to determine whether the value of 0.39 can be rejected as too low for husbands in New Orleans. Be sure to state your hypotheses, all relevant statistics, a list of technical conditions, and a conclusion to your test. b. Produce a relevant confidence interval designed to capture the true proportion of American husbands who do not know the color of their wives' eyes. Explain how your interval backs up the result of your test of significance from part a.

These next questions come after part B. Which of the statements correctly describes the relationship between the mean and median in the histogram of the number of servings of fruit per day claimed by the 7474 seventeen‑year‑old girls? A) The mean and median are about equal because the distribution is right‑skewed. B) The mean is larger than the median because the distribution is right‑skewed. C) The median is larger than the mean because the distribution is right‑skewed. D) There is not enough information to tell us about the relationship between the mean and median in the histogram. (c) In general, you cannot find the exact values of median, quartiles, or mean from the histogram. What is special about the histogram of the number of servings of fruit that allows you to do this? Select an answer choice. A) We know exactly how many observations fall in each bin because of the way the bins are constructed. B) The sample size only consists of only 74…
Regarding the context regarding the coronavirus pandemic, see the table below, which refers to 5 groups of people infected with the coronavirus and the number of deaths in each group. a) You, student, by observing the data tabulated in the table above, come to what conclusion about the absolute frequency of the second grade? b) João, a person observing the table, calculates and states that the relative frequency of the fourth class is 48.46% and informs that 48.46% of the number of deaths occurred in the group with the number greater than or equal to 70 and less than or equal to 80 infected. Do you agree with João's calculation and interpretation? If you agree or disagree, provide the calculation and interpretation that justifies your choice. c) Going deeper, Maria, another person who looks at the table, interprets that 16 deaths occurred in the group with a number greater than or equal to 40 and less than 70 infected people. When you see this interpretation that Maria made, do you…
