A group of people were given a personality test to determine if they were Type A or Type B. The results are shown in the table below:



alg 2

A company offered one half of its employees a bonus if the production of cookies increased by 15%. The other half of the employees was not offered a bonus. As the end of the month, production in the group that did not get the bonus offer increased by a mean of 20 and production in the bonus group increased by a mean of 10.



What is the correct order of steps to determine if the results are significant?





A: Calculate the probability of a difference of 10.





B: Calculate the difference of the means.

1.) A biologist is comparing the growth of a population of flies per week to the number of flies a bullfrog will consume per week. She has devised an equation to solve for which day (x) the bullfrog would be able to eat the entire population. The equation is 2x = 3x - 1. However, she has observed that the bullfrog cannot eat more than seven flies in one week.Explain to the biologist how she can solve this on a graph using a system of equations. Identify any possible constraints to the situation.
