Answer:
<em>The data point is </em><em>1.6</em><em> standard deviations above the mean.</em>
Step-by-step explanation:
Z-score
It is the number of standard deviations from the mean that a data point is. It's a measure of how many standard deviations below or above the population mean a raw score is.
A Z-score is also known as a standard score and it can be placed on a normal distribution curve.
As in this case the Z-score is +1.6, so it means the data point is 1.6 standard deviations above the mean.
Answer:
The average defective rate = .057
Step-by-step explanation:
Given -
Sample size n = 100
