Problem 83

Given information

Here, the mean of the given distribution (μx)=$4.59; the standard deviation (σx)=$0.10;

The sample size(n)=16; We need to compute P(X >4.69)=?

Step-by-step explanation

Here, (μx)=$4.59;

So, the standard deviation for the mean;

The corresponding z-value is calculated using Central Limit Theorem

;

z=(4.69 - 4.59)/0.025 = 4;
