Determine the two z-scores that divide the area under the standard normal curve into a middle 0.11 area and two outside 0.445 areas.
In a normal distribution N(0,1), what are the two z-scores that will be the lower and upper boundaries for the middle 90 percent of the distribution? Choose the listed values that are the closest to your calculated value! - 1.96 and + 1.96 - 1.96 and + 1.65 - 2.58 and + 2.58 - 2.00 and + 2.58 - 1.65 and + 1.65 - 2.00 and + 2.00
What Z-scores correspond to separating middle 60% of the normal distribution from the rest of the distribution?
