Standard deviation of a normal data distribution is a _______. Group of answer choices

FrozenT [24]

Answer:

Standard deviation of a normal data distribution is a measure of data dispersion.

Step-by-step explanation:

Standard deviation is used to measure dispersion which is present around the mean data.

The value of standard deviation will never be negative.

The greater the spread, the greater the standard deviation.

Steps-

1. At first, the mean value should be discovered.

2.Then find out the square of it's distance to mean value.

3.Then total the values

4.Then divide the number of data point.

5.the square root have to be taken.

Formula-

SD= $\sqrt{\frac{(\sum{x-x)^2} }{n-1}$

Advantage-

It is used to measure dispersion when mean is used as measure of central tendency.

Water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. Which would not be a proportion you could use to solv

enot [183]

Answer: See explanation

Step-by-step explanation:

You didn't give the options but let me help out.

First, we need to convert 2 2/3 hours to minutes. This would be:

= 2 2/3 × 60 minutes

= 8/3 × 60 minutes

= 160 minutes

Since water goes over a waterfall at a rate of 162 1/2 gallons every 15 minutes. The the gallons of water going over the waterfall in 2 2/3 hours would be:

= (162 1/2 × 2 2/3hours) / 15 minutes

= (162 1/2 × 160) / 15

= 1733 1/3 gallon
