Question

The measurements on height have to be converted from inches to centimeters for publication in a British journal. The mean in the study was 68 inches and the standard deviation was 10 inches. What should the reported mean and variance be

Answer 1

Answer:

mean = 172.72cm and variance = 645.16

Step-by-step explanation:

1 inch = 2.54 centimetres

mean = 68 * 2.54 = 172.72 cm

standard deviation = 10 *2.54 = 25.4 cm

variance = square of standard deviation

variance = 25.4 * 25.4

variance = 645.16 cm
