A vertical line drawn through a normal distribution at z = –0.80 will separate the distribution into two sections. The proportion in the larger section is 0.7881. true or false?

Answer 1

Note that Z score represents the "X value" = to be the number of standard deviations from the mean, in this case below the mean (-.8).

Use any normal distribution calculator http://onlinestatbook.com/2/calculators/normal_dist.html and find the area to the right of the -0.8 point to be 0.7881 thus the correct response is true.
