Explain the circumstances for which the interquartile range is the preferred measure of dispersion. What is an advantage that th
KatRina [158]

Answer:

Explain the circumstances for which the interquartile range is the preferred measure of dispersion

Interquartile range is preferred when the distribution of data is highly skewed (right or left skewed) and when we have the presence of outliers. Because under these conditions the sample variance and deviation can be biased estimators for the dispersion.

What is an advantage that the standard deviation has over the interquartile​ range?

The most important advantage is that the sample variance and deviation takes in count all the observations in order to calculate the statistic.

Step-by-step explanation:

Previous concepts

The interquartile range is defined as the difference between the upper quartile and the first quartile and is a measure of dispersion for a dataset.

IQR= Q_3 -Q_1

The standard deviation is a measure of dispersion obatined from the sample variance and is given by:

s=\sqrt{\frac{\sum_{i=1}^n (X_i -\bar X)^2}{n-1}}

Solution to the problem

A board that measures 3/4 feet long is cut into 6 equal pieces. What is the length of each piece?
shusha [124]

Answer:

See below:

Step-by-step explanation:

So we know that there is a \frac{3}{4} feet long board and that it is split into 6 pieces.

With that information, we can split it by doing the following:

1. \frac{3}{4} *\frac{1}{6}

We can do this because we have a board that is 0.75 feet long and we multiply it by one sixth because we want to divide a fraction and to do that we have to flip the fraction.

After doing that, we get our answer of \frac{3}{24}=\frac{1}{8}

This means that each piece is \frac{1}{8} feet long.

Cheers!

Determine if the two functions f and g are inverses of each other
Margarita [4]

Answer:

Yes.

Step-by-step explanation:

f(g(x))

f(\frac{x-12}{9})  

( I will have to replace all x's in 9x+12 with (\frac{x-12}{9})

9(\frac{x-12}{9})+12

(x-12)+12

x-12+12

x+(-12+12)

x+0

x

So the answer is yes.
