given a normal distribution with U=51 and =4. between what two X-values are 70% of the values

Solutions

Expert Solution

Given that it is normally distributed with mean= 51 and standard deviation =4 hence to find the X values within which the 70 % values lie is calculated using Z value at the left of the 70 % area and to the right of the 70% area.

And the Z values at the Lower end of 70% of the value is computed using the Z table shown below as

-1.04 hence The x value is calculated as

similarly, the right end would be

Z= 1.04

hence
