The most appropriate measure of variability for this data set is the IQR,
Option B is the correct answer.
What is the interquartile range?An interquartile range is a measure of the difference between the upper and lower quartiles of a dataset.
W can find the values of the upper and lower quartile and median from a box plot.
The middle line is the median and the first line is the lower quartile and the last line is the upper quartile.
The formula used is Upper quartile - Lower quartile.
We have,
To determine the appropriate measure of variability for the given data, let's first calculate some descriptive statistics:
Mean: (5 + 8 + 10 + 12 + 12 + 19) / 6 = 11
Median: the middle value is 11, since there are an even number of values
Range: the difference between the maximum value (19) and the minimum value (5) is 14
Interquartile range (IQR): Q3 (the third quartile) is the median of the upper half of the data, which is (12, 12, 19), and Q1 (the first quartile) is the median of the lower half of the data, which is (5, 8, 10). Thus, Q3 = 12 and Q1 = 8, and the IQR is 12 - 8 = 4.
Now, we need to determine which measure of variability is most appropriate for this data set.
Option A suggests using the range, which is the difference between the maximum and minimum values.
The range is affected by outliers and extreme values, and in this data set, the value of 19 is significantly larger than the other values, which might make the range an unreliable measure of variability.
Option B suggests using the IQR, which is a measure of the spread of the middle 50% of the data.
The IQR is less affected by extreme values than the range and is often preferred when there are outliers or skewed distributions.
Option C suggests using the mean, which is a measure of central tendency, not variability.
Option D suggests using the median, which is also a measure of central tendency, not variability.
Therefore,
The most appropriate measure of variability for this data set is the IQR,

Given,
Distance covered by hurricane = 130 miles
Then time = [tex]\frac{6}{12}[/tex] hours=[tex]0.5[/tex] hour
Distance=Speed*Time
Speed=[tex]\frac{Distance}{Time}[/tex]

A regular polygon is shown with one of its angle measures labeled a. If m∠a = (2z + 64)°, find the value of z.
Answer:
the sum of all the angles of the polygon is 180°
Then,

2z = 180° - 64°
2z = 116°
z = 116 / 2

Step-by-step explanation:
At a restaurant, hot chocolate can be purchased in two different cup sizes. A 12-ounce cup costs $4.80 and a 16-ounce cup costs $6.40.
Is the linear relationship between cup size and cost also proportional? Why or why not?
Yes, there is no constant of proportionality.
Yes, the constant of proportionality is 0.4.
No, the constant of proportionality is 0.4.
No, there is no constant of proportionality.
Answer:
Yes, the constant of proportionality is 0.4.
Step-by-step explanation:
[tex] \frac{4.80}{12} = \frac{48}{120} = \frac{2}{5} = .4[/tex]
[tex] \frac{6.40}{16} = \frac{64}{160} = \frac{2}{5} = .4[/tex]
Yes, the given relation is proportional with a constant of proportionality is 0.4 thus option (B) is correct.
What are the ratio and proportion?The ratio is the division of the two numbers.
For example, a/b, where a will be the numerator and b will be the denominator.
Proportion is the relation of a variable with another. It could be direct or inverse.
As per the given,
A 12-ounce cup costs $4.80.
The ratio of cost to ounce = 4.80/12 = 0.4
A 16-ounce cup costs $6.40.
The ratio of cost to ounce = 6.40/16 = 0.4
So constant of proportionality is 2.5.
Hence "Yes, the given relation is proportional with a constant of proportionality is 0.4".
