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 5 4 4 5 3 7 5 6 9 5 1 9 7 3 6 9 4 6 5 2 8 0 8 9 6 4 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 property

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 plot

Find the value of the third quartile on the given box - and - whisker plot. (Since the plot is not actually shown here, assume we are able to read it). Let's say after reading the plot we find that the value of $Q_3$ is 7.5.

Answer:

7.5
