Answer 1

Answer:

84%

Step-by-step explanation:

The mean has 50% below the mean and 50 % above the mean

The mean is 103.47

The standard deviation is 4.07

Add the mean and the standard deviation

103.47+4.07 = 107.54

We want to know how much data is below the mean plus one standard deviation

Within one standard deviation is 68% , but that is on both sides, we are  only needed on the right side so we need 1/2 of the 68 = 34

50+34 = 84

Answer 2

The mean 103.47
The stander deviation 4.07

1/2*68=34
The percent of time will be 80
34+50=80
