Pizza delivery times at pizza time are normally distributed with a mean time of 27 minutes and a standard deviation of 3 minutes. using the empirical rule, approximately what percent of pizzas are delivered between 24 and 30 minutes?
32%
68%
95%
99.7%

Second Option

68%

Step-by-step explanation:

First we calculate the Z-scores

We know the mean and the standard deviation.

The mean is:

The standard deviation is:

The z-score formula is:

For x=24 the Z-score is:

For x=30 the Z-score is:

Then we look for the percentage of the data that is between deviations from the mean.

According to the empirical rule 68% of the data is less than 1 standard deviations of the mean.  This means that 68% of pizzas are delivered between 24 and 30 minutes

answer:   rotate 270° clockwise about (7, 1) and reflect across the line x = 7
