The ages of the winners of a cycling tournament are approximately bell-shaped. The mean age is 27.5 years, with a standard deviation of 3.6 years. The winner in one recent year was 32 years old. (a) Transform the age to a z-score. (b) Interpret the results. (c) Determine whether the age is unusual. (Type an integer or decimal rounded to two decimal places as needed.) (b) Interpret the results. An age of 32 is about 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. OC. Yes, this value is unusual. A z-score outside of the range from -2 to 2 is unusual. O D. No, this value is not unusual. A z-score between -2 and 2 is not unusual.

Confidence Intervals

When we calculate intervals in probability and statistics, it can be simply termed as finding out a confidence interval. The confidence interval is usually calculated from the data set which is observed. The value of the parameter that needs to be calculated is present here only.
