The answer should be 1 3/8
Answer: 0.22
Step-by-step explanation:
We know that the best point estimate for the difference between two population mean is the difference between their sample means.
Given : For the 39 randomly selected upperclassmen, the sample mean was 0.12 and sample standard deviation was 0.42. For the 35 randomly selected underclassmen, the sample mean was 0.34 and the sample standard deviation was 0.87.
Let A denotes the population of upperclassmen and B denotes the population of underclassmen .


Then, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen will be :-

Hence, the point estimate of the difference in the population mean volunteered between underclassmen and upperclassmen =0.22

Hey there!
“The quotient of -9 and y”
• Facts When you come across the word “QUOTIENT” in algebra/ math in general it usually MEANS you’re DIVIDING both your numbers by each other
• Guide: -9 will be your numerator and y would be your denominator (or -9 would be in your front whereas y will be in the back)
So, based on your guide we have your ANSWER should look like: “-9 ÷ y”
