Guys please help i'm stup!d
Nataly [62]

Answer:

Option B: 0.4

Step-by-step explanation:

We have 20 dots.

Such that each column represents the repetitions for each proportion.

So:

0.1 -> 3 times

0.2 -> 1 time

0.3 -> 4 times

0.4 -> 6 times

0.5 -> 3 times

0.6 -> 3 times

Now we can compute the mean of these values, and that will be the best estimation we can make with the given data.

Remember that for a set of N values:

{x₁, x₂, ..., xₙ}

The mean is:

M = \frac{x_1 + x_2 + ... + x_n}{N}

In this case we have the set of 20 points described above, then the mean is:

M = \frac{3*0.1 + 1*0.2 + 4*0.3 + 6*0.4 + 3*0.5 + 3*0.6}{20} = 0.37

Rounding to the first place after the decimal point, we get:

M = 0.4

Then the correct option is option B.

The difference of the range and the interquartile range of the data set represented by the box plot is
Varvara68 [4.7K]

Answer:

R - IQR = 10

Step-by-step explanation:

The interquartile range is IQR is:

IQR = Q_3 -Q_1

Where:

Q_3 = third quartile

Q_1 = first quartile

So the interquartile range is the difference between the highest quartile and the lowest quartile. In other words, it is the width of the box in the diagram.

So:

IQR = 29 -21\\IQR = 8

The R range is the difference between the highest value and the lowest. In other words:R = 34 -16\\R = 18

Finally:

R - IQR = 18 - 8 = 10
