FourFour hundred different voters in a region with two major political parties, A and B, are randomly selected from the population of 6500 registered voters. Each is asked if he or she is a member of political party A, recording Yes or No. Choose the correct answer below. A. No, the number of trials is not fixed. B. No, the probability of success is not the same in all trials. C. No, there are more than two possible outcomes. D. Yes the result is a binomial probability distribution. E. No the trials are not independent and the sample is more than 5 % of the population. Question 11 Assume the readings on thermometers are normally distributed with a mean of 0degrees°C and a standard deviation of 1.00degrees°C. Find the probability that a randomly selected thermometer reads between −2.23 and −0.77 and draw a sketch of the region. The probability is nothing. (Round to four decimal places as needed.) Question 12 A survey found that women’s heights are normally distributed with mean 63.5 in and standard deviation 2.2 in. A branch of the military requires women’s heights to be between 58 in and 80 in. a. Find the percentage of women meeting the height requirement. Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? b. If this branch of the military changes the height requirements so that all women are eligible except the shortest 1% and the tallest 2%, what are the new height requirements? a. The percentage of women who meet the height requirement is ???%. (Round to two decimal places as needed.) Are many women being denied the opportunity to join this branch of the military because they are too short or too tall? A. No, because the percentage of women who meet the height requirement is fairly small. B. Yes, because the percentage of women who meet the height requirement is fairly large. C. Yes, because a large percentage of women are not allowed to join this branch of the military because of their height. D. No, because only a small percentage of women are not allowed to join this branch of the military because of their height. b. For the new height requirements, this branch of the military requires women’s heights to be at least ??? in and at most ??? in. (Round to one decimal place as needed.)
