A financial analyst determines the yearly research and development investments for 50 blue chip companies. She notes that the distribution is distinctly not bell-shaped. If the 50 dollar amounts are converted to z-scores, what can be said about the standard deviation of the 50 z-scores?

standard deviation of the 50 z-scores will equal to 1

Explanation:

Data provided in the question:

The 50 dollars amount is converted to z-score

Now,

The z-score follows the distribution in which the mean is 0 and the value of the standard deviation is 1.

The above value does not get affected due to any distribution of raw scores.

Therefore,

The standard deviation of the 50 z-scores will equal to 1
