Wait times at an orthodontist’s office are typically 17 minutes, with a standard deviation of 2 minutes. What percentage should be seen by the doctor between 11 and 23 minutes for this to be considered a normal distribution?

0.997

Step-by-step explanation:

The mean wait times at an orthodontist’s office are typically 17 minutes, with a standard deviation of 2 minutes.

We want to find the percentage that should be seen by the doctor between 11 and 23 minutes for this to be considered a normal distribution.

We know that 23= 17+3(2), is 3 standard deviation above the mean.

Also, 11=17-3(2), is 3 standard deviation below the mean.

According to the empirical rule, approximately 99.7% of the distribution are within 3 standard deviations of the mean.

step-by-step explanation:

the x's and the y's both go up the same amount each time, therefore it will be a linear function because it will go in a straight line when drawn on a graph.

hope this !
