Answer 1

The z-score of 1 and 3 are 9.2 and 11.6, respectively.

Using the z-score table, we may see that the probability that the data is below the z-score of 1 and 3 are 0.84134 and 0.99865.

Thus, to obtain the probability between the two, simply subtract the two probabilities. Thus, we obtain the following.

`0.99865-0.84134=0.15731=15.731\%`

Or approximately, it is 0.1585 or 15.85%.
