The ages of a sample of Canadian tourists flying from Toronto to Hong Kong were: 31, 23, 57, 41, 52, 14, 77, 51, 34, 40 (Round range to nearest whole number and standard deviation to 2 decimal places.) a. Compute the range. Range b. Compute the standard deviation. Standard deviation Explanation: a. The range is the difference between the largest and smallest value or 63, found by 77 – 14. b. The sample mean is 13.80, found by 138/10 where 2formula50.mml = 42.00 The differences between each value and the mean are: -11.0, -19.0, 15.0, -1.0, 10.0, -28.0, 35.0, 9.0, -8.0 and -2.0, respectively. Their squares are 121.00, 361.00, 225.00, 1.00, 100.00, 784.00, 1,225.00, 81.00, 64.00, and 4.00. The sum of the squares is 2,966.0. So the sample variance is 329.556, found by 2,966.0/9 and the sample standard deviation is the square root of that number or 18.1537.

a.	Compute the range.

Range

b.	Compute the standard deviation.

Standard deviation

Explanation:

a.

The range is the difference between the largest and smallest value or 63, found by 77 – 14.

b.

The sample mean is 13.80, found by 138/10 where  = 42.00

The differences between each value and the mean are: -11.0, -19.0, 15.0, -1.0, 10.0, -28.0, 35.0, 9.0, -8.0 and -2.0, respectively. Their squares are 121.00, 361.00, 225.00, 1.00, 100.00, 784.00, 1,225.00, 81.00, 64.00, and 4.00. The sum of the squares is 2,966.0. So the sample variance is 329.556, found by 2,966.0/9 and the sample standard deviation is the square root of that number or 18.1537.
