A psychologist uses two types of boxes with mice and rats. The amount of time (in minutes) that each mouse and each rat spends in each box per day is given in the table. What is the maximum number of mice and rats that can be used in the experiment? How many mice and how many rats produce this maximum?| | Time | Maximum Time ||-------|--------------|---------------|| | Mice | Rats | Available per Day || Box A | 20 min | 10 min | 840 min || Box B | 10 min | 20 min | 720 min |What is the maximum number of mice and rats that can be used in the experiment? ∎Explanation of the Table:- **Box A**: Each mouse spends 20 minutes per day, and each rat spends 10 minutes per day. The total maximum time available for Box A is 840 minutes per day.- **Box B**: Each mouse spends 10 minutes per day, and each rat spends 20 minutes per day. The total maximum time available for Box B is 720 minutes per day.This setup aims to determine the optimal number of mice and rats so that the total time spent by all animals does not exceed the available daily time for each box.

For a statistics class project, Jonathan and Crystal held an ice-cream-eating contest. They randomly selected 29 males and 35 females from their large high school to participate. Each student was given a small cup of ice cream and instructed to eat it as fast as possible. Jonathan and Crystal then recorded each contestant's gender and time (in seconds), as shown in the dotplots. : ● Male Female 15 75 90 105 30 45 60 Time to eat ice cream (sec) Do these data give convincing evidence of a difference in the population means at the a = 0.10 significance level?
