Question

The amount of time (in hours) that Sam studied for an exam on each of the last five days is given below. 1.7 7.7 8.3 1.6 5.1 Find the mean study time.

Answer 1

Answer:

The mean is 4.88 hours / day

Step-by-step explanation:

To calculate the mean we just add the values and divide by the number of items (in this case we add the hours and divide by the number of days)

so the equation would be

$\frac{1.7+7.7+8.3+1.6+5.1}{5}=4.88$
