Question

The following data shows the number of hours $24$ students of a class spent studying per day.

$4$	$3$	$4$	$6$	$1$	$4$	$0$	$5$
$3$	$1$	$4$	$4$	$1$	$4$	$5$	$6$
$0$	$3$	$4$	$0$	$4$	$0$	$3$	$3$

Using the grid below, draw a dot diagram to represent the above data.
What is the modal number of hours the students spent studying?
Calculate the mean number of hours the students spent studying.
If the above data was presented on a pie chart, what is the size of the angle that represents the number of students who study at least $3$ hours a day?
What is the probability of a student studying $4$ hours a day?

Accepted Answer

(a) Dot frequencies for $0$ to $6$ hours: $4,3,0,5,8,2,2$ (b) $4$ hours (c) $3$ hours (d) $255^\circ$ (e) $\frac{1}{3}$
