the data show the number of hours spent studying per day by a sample of 28 students. use the box - and - whisker plot below to answer parts (a) through (c) below.
1 11 9 3 9 6 7 6 9 4
9 1 0 7 6 5 8 1 9
9 5 8 4 7 7 8 1 6
click the icon to view the box - and - whisker plot.
(a) about 75% of the students studied no more than how many hours per day?
about 75% of the students studied no more than hours per day.
(type an integer or decimal rounded to one decimal place as needed.)

Explanation:

Step1: Recall box - and - whisker plot properties

In a box - and - whisker plot, the third quartile ($Q_3$) represents the value below which 75% of the data lies.

Step2: Locate $Q_3$ on the box - and - whisker plot

Once the box - and - whisker plot is viewed, identify the value of the upper edge of the box which is $Q_3$.

Answer:

(The value of $Q_3$ from the box - and - whisker plot, which is not provided in full here. But in general, it is the value you read from the upper - edge of the box in the box - and - whisker plot. For example, if from the plot $Q_3 = 8$, then the answer is 8)
