Effects of Transforming Inches to Centimeters

APSTAT-GNJV9Z

Incoming freshmen at a large high school routinely have their heights measured by the school nurse. The nurse records each height in inches and then determines the standardized z-score for each student.

How would the z-scores be affected if each height was converted from inches to centimeters? NOTE: $1 \text{ inch} = 2.54\text{ cm}$​

A

The z-scores will remain unchanged.

B

The z-scores will all be multiplied by $2.54$.

C

All z-scores will be increased by $1.54$.

D

All z-scores will be $254$% of their previous values.

E

There is no way to predict what will happen to the z-scores.
