-1 is less than 0, so you use the first equation:
3(-1) +2 = -3+2 = -1
f(-1) = -1
For 0 use the 2nd equation:
3(0) + 4 = 0+4 = 4
f(0) = 4
For 2 use the 2nd equation:
3(2) + 4 = 6+4 = 10
f(2) = 10
I belive your actually right and the letter answer is H (im really not sure)
Answer: NO.
Step-by-step explanation:
We know that , the 95% confidence interval indicates that the researcher can be 95% sure that the true value of population mean falls in it.
Given : A company is interested in estimating the costs of lunch in their cafeteria.
After surveying employees, the staff calculated that a 95% confidence interval for the mean amount of money spent for lunch over a period of six months is ($720, $900).
Then, the correct interpretation would be : The company can be 95% sure that the true value of population mean falls in it.
