Step-by-step explanation:

so his class lasts 2 5/6 hrs...and he has already been in there for 1 2/5 hr

so the time he has left can be found by subtracting the time he has been there from the total time of the class

2 5/6 - 1 2/5....

Answer:

89.04% of the data points will fall in the given range of z = − 1.6 and z = 1.6

Step-by-step explanation:

We are given a normally distributed data.

We have to find the percentage of data that lies within the range z = − 1.6 and z= 1.6

Formula:

$z_{score} = \displaystyle\frac{x-\mu}{\sigma}$

$P(-1.6 \leq z \leq 1.6)\\= P(z \leq 1.6) - P(z \leq -1.6)\\\text{Calculating the value from standard normal table}\\= 0.9452 - 0.0548 = 0.8904= 89.04\%$

89.04% of the data points will fall in the given range of z = − 1.6 and z= 1.6
