Answer to Problem 30HP
The average time taken to learning video game by boys is less than girls.
Explanation of Solution
Given information:
Collect and organize the data and calculate the sample statistic.
Calculation:
A study invesigated whether boys are quicker at learning video game than girls. Then ten boys and ten girls are randomly selected to play video game bothe groups had never played before. Then observations was recored on their expertise.
Objective: the objective of the study is to determine whether boys are quicker at learning video game than girls.
Population: the population of the experiment is all boys and girls.
Data: table shows the data for time taken by each boy and girl to learn video game.
Hence, the average time taken to learning video game by boys is less than girls.
