Given information

From the previous task the total number of pages read is normally distributed with a mean of 962 and a standard deviation of 32 pages.

Step-by-step explanation

Step 1.

Notice that 1050 pages is more than 2 standard deviations more than the mean of 962.

Therefore, using the empirical law of the normal distribution, there is less than a 2.5% chance of a data value lying more than 2 standard deviations above the mean.

Thus, it is very unlikely that the professor will read more than 1050 pages.
