y = mx + b
(0, b) y-intercept
m = 
~~~~~~~~~~
( - 2, 13)
(0, <em>5</em>) <----- y-intercept
(3, - 7)
(4, - 11)
<em>m =</em> 
= <em>- 4</em>
<em>y = - 4x + 5</em>
Answer:
68%
Step-by-step explanation:
The mean is 32 minutes, and the standard deviation is 4 minutes.
28 is 1 standard deviation below the mean, and 36 is 1 standard deviation above the mean.
According to the empirical rule, 68% of a normal distribution is between -1 and 1 standard deviations. 95% is between -2 and 2 standard deviations. 99.5% is between -3 and 3 standard deviations.
So the answer is 68%.
