You have been contracted from a company to do a study. From previous experience with the populations, it is known that the variance for population 1 is 100 and the variance for population 2 is 64. You decide to collect 100 samples from population 1 and found that the mean was 70. You also take 100 samples from population 2 and the mean of that sample is 68. The company has told you that they believe there is a difference in means. a.) Conduct a hypothesis test to find if there is any difference in means with alpha

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
