Height, in meters, is measured for each person in a sample. after the data are collected, all the height measurements
are converted from meters to centimeters by multiplying each measurement by 100. which of the following statistics
will remain the same for both units of measure?
(a) the mean of the height measurements
(b) the median of the height measurements
(c) the standard deviation of the height measurements
(d) the maximum of the height measurements
(e) the z-scores of the height measurements

(E) The z-scores of the height measurements

Step-by-step explanation:

Mean is given by

Where,

n = Number of people

= The heights of people

When converting m to cm the mean would be

So, the mean would change

The median gives us the middle data value when the data values are in ascending order.

So, the median would change

Standard deviation

When converting to centimeters

Hence, the standard deviation would change

When converting to centimeters the maximum height in meters would be the maximum height in centimeters also.

The z score is given by

where,

x = Data point

= Mean

= Standard deviation

When converting to centimeters

Hence, the z score would remain the same

2 5/8 is the final answer! : )

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
