The ages of the winners of a cycling tournament are approximately bell-shaped. The mean age is 28.2 years, with a standard deviation of 3.2 years. The winner in one recent year was 31 years old. (a) Transform the age to a z-score. (b) Interpret the results. (c) Determine whether the age is unusual. (a) Transform the age to a Z-score. z= (Type an integer or decimal rounded to two decimal places as needed.) (b) Interpret the results. An age of 31 is standard deviation(s) V the mean. (Type an integer or decimal rounded to two decimal places as needed.) (c) Determine whether the age is unusual. Choose the correct answer below. O A. Yes, this value is unusual. A z-score between - 2 and 2 is unusual. O B. No, this value is not unusual. A z-score outside of the range from - 2 to 2 is not unusual. O C. No, this value is not unusual. A z-score between -2 and 2 is not unusual. O D. Yes, this value is unusual. A z-score outside of the range from - 2 to 2 is unusual.
