A z-score of +1.6 represents a value which is how many standard deviations above the mean?

Olegator [25]

Answer:

The data point is 1.6 standard deviations above the mean.

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.

The results of inspection of DNA samples taken over the past 10 days are given below. Sample size is 100.

ASHA 777 [7]

Answer:

The average defective rate = .057

Step-by-step explanation:

Given -

Sample size n = 100

Day - 1 2 3 4 5 6 7 8 9 10

Defectives - 7 6 6 9 5 6 0 8 9 1

The average defective rate is the no of defective in each day for past ten days

The average defective rate = $\frac{\sum no\; of \; effective \; in\; each\; day}{no\; of \; day \times n}$

= $\frac{7 + 6 + 6 + 9 + 5 + 6 + 0 + 8 + 9 + 1}{10\times 100}$

= $\frac{57}{1000}$

= .057
