Find the interquartile range of the data.

likoan [24]

The answer is 14. Here is how I work it out.

First we are going have to identify quartile 1 and quartile 3.

So after putting the numbers in order from least to greatest mark the number with a half way point.

This is optional but it will help us spot the sections better.

31,33,35,41,43,|46,48,49,49,50

Next put parentheses around the remaining groups of numbers.

(31,33,35,41,43,)|(46,48,49,49,50)

For the next step we have to find the median of each group.

(31,33,35,41,43,)|(46,48,49,49,50)

The median of each group, are called the quartiles, the median of the lower half is quartile 1, and the median of the upper half is quartile 3.

Now subtract quartile 1 from quartile 3.

49 – 35 = 14

So the interquartile range of this data set is 14.

If an object has a density of less than $1$ g/ml, the object will float in water.

So, fourth option is correct

$Density = \frac{Mass}{Volume}$

The object with density less than $1$ g/ml will float, and the object with a density more than $1$ g/ml will sink.

So, if an object has a density of less than $1$ g/ml, the object will float in water.

Therefore, fourth option is correct
