Question

The line plot below shows a number of ounces of juice Daniel poured into glasses which shows the number of ounces Daniel would have poured if he had poured the same amount in each glass

Answer 1

The question is an illustration of mean or averages.

If he pours equal amount in the glasses, $8\frac{3}{4} oz$ would be in each glass

I've added as an attachment, the missing line plot.

The data on the line plot can be represented as follows:

$\left[\begin{array}{cccccccc}x&7&7\frac 12&8&8\frac12&9&9\frac 12 & 10 \\f&0&0&2&1&4&1&0\end{array}\right]$

Where:

$x \to$ the glasses

$f \to$ number of ounces

Glasses with no x on the line plot have a frequency of 0.

If he pours an equal amount of ounces in each glass, the amount in each glass is the mean.

The mean is then calculated as:

$\bar x = \frac{\sum fx}{\sum f}$

So, we have:

$\bar x = \frac{0 \times 7 + 7\frac 12 \times 0 + 8 \times 2 + 8\frac 12 \times 1 + 9 \times 4 + 9\frac 12 \times 1 + 10 \times 1}{0 + 0 + 2+1+4+1+0}$

$\bar x = \frac{0 + 0 + 16 + 8\frac 12 + 36 + 9\frac 12+ 10}{8}$

$\bar x = \frac{70}{8}$

Simplify

$\bar x = 8\frac{3}{4}$

Hence, if he pours equal amount in the glasses, $8\frac{3}{4} oz$ would be in each glass
