determine whether the body is on the right or left side of t

determine whether the body is on the right or left side of the line, find the proportion in the body

z=1.2 hours per day

vertical line 1.2 standard deviations to the right of the mean. So, the body is on the left side of the line and the proportion in the body is

1-P(z<1.2)=0.1151

z=2.58

vertical line 2.58 standard deviations to the right of the mean. So, the body is on the left side of the line and the proportion in the body is

1-P(z<2.58)=0.0049

z=0.55

vertical line 0.55 standard deviations to the right of the mean. So, the body is on the left side of the line and the proportion in the body is

1-P(z<0.55)=0.2912

z=-0.50

vertical line 0.50 standard deviations to the left of the mean. So, the body is on the right side of the line and the proportion in the body is

P(z<-0.50)=0.3085

z= - 0.77

vertical line 0. 77 standard deviations to the left of the mean. So, the body is on the right side of the line and the proportion in the body is

P(z<-0.77)=0.2206
