I would answer but I don’t see the options to choose... can you tell me?
Hello!
to find a percent, convert the percent to a decimal by dividing by 100
13.8 / 100 = 0.138
then multiply the divided percent by the number you needed to find the percentage of
$29.90 * 0.138 = $4.1262
since you're using currency, round the the nearest hundredth
your final answer is $4.13
I hope this helps, and have a nice day!
The statements that are true about this study are:
- This study uses random sampling.
-
This study uses a control group.
-
This study uses a repeated measures design.
Random sampling occurs when each sample has an equal probability of being chosen in a study.
This is seen in the random selection of 100 children. The Control group was used with the first group that had no screen time.
The repeated measures design was also used when multiple measurements were taken during different weeks.
