Randomization in an experiment Is important because it ensures that the treatments have an effect on the response. the individuals who will be in the study were chosen randomly. the groups of subjects are similar, on average, in all respects before applying the different treatments to the different groups. each individual has a fair chance of being included in the study. each treatment is thought of as a value of the explanatory variable.

after simplifying it i got: -36.25 as my answer. hope that !

the camry sales+accord sale=828,000. to make it so the two numbers are 18 thousand apart and still equal 828,000, you first need to find out what half of 828,000 is. 828,000/2=414,000. for the two numbers to equal 828,000, you have to add the same amount as you subtract from the middle. in this case, the number is 9,000 because it's half of 18,000. to equal 828,000, you have to add 9,000 to 414,000 for the camry and subtract 9,000 from 414,000 for the accord. 414,000+9,000=423,000.

414,000-9,000=405,000.

423,000+405,000=828,000.

423,000-405,000=18,

hope it
