17. According to a website, the mean weight of an adult member of a particular breed of dog is 154 pounds. Assume the distribution of weights is Normal with a standard deviation of 8 pounds. a. Find the standard score associated with a weight of 170 pounds. b. Using the Empirical Rule and your answer to part a, what is the probability that a randomly selected dog of this breed weighs more than 170 pounds? c. Use technology to confirm your answer to part b is correct. d. Almost all adult dogs of this breed will have weights between what two values? a. The standard score associated with a weight of 170 pounds is z = (Type an integer or decimal rounded to two decimal places as needed.) b. According to the Empirical Rule, the probability that a selected dog of this breed weighs more than 170 pounds is about (1) c. Using technology, the probability that a selected dog of this breed weighs more than 170 pounds is which (2) close to the value obtained in part b. (Type an integer or decimal rounded to one decimal place as needed.) %. d. Almost all adult dogs of this breed will have weights between (3) (1) 5 O 0 (4) (2) O is O is not 2.5 O 16 95 68 32 (3) 138 146 130 154 0000 170. 178. 162. 154. and (4) 18. According to a human modeling project, the distribution of foot lengths of 16- to 17-year-old boys is approximately Normal with a mean of 25.4 centimeters and a standard deviation of 1.3 centimeters. In the United States, a man's size 11 shoe fits a foot that is 27.9 centimeters long. What percentage of boys of this age group will wear a size 11 shoe or larger? The percentage of boys 16- to 17-years-old who wear a size 11 shoe or larger is (Round to one decimal place as needed.) 19. According to a human modeling project, the distribution of foot lengths of 16- to 17-year-old boys is approximately Normal with a mean of 25.3 centimeters and a standard deviation of 1.5 centimeters. Suppose a shoe store stocks shoes in men's sizes 7 through 12. These shoes will fit men with feet that are 24.6 to 28.8 centimeters long. What percentage of boys aged 16 to 17 will not be able find shoes that fit in this store? The percentage of boys 16- to 17-years-old who will not be able to find shoes that fit in the store is (Round to one decimal place as needed.) %.
