Answer: ($3.055, $3.205)
Step-by-step explanation:
Given : Significance level : 
Critical value : 
Sample size : n= 36
Sample mean : 
Standard deviation : 
The confidence interval for population mean is given by :_


Hence, the 95% confidence interval to estimate the population mean = ($3.055, $3.205)
f(-2) = 2(-2)² - 8(-2) + 6 = 30
f(-1) = 2(-1)² - 8(-1) + 6 = 16
f(0) = 2(0)² - 8(0) + 6 = 6
f(1) = 2(1)² - 8(1) + 6 = 0
f(2) = 2(2)² - 8(2) + 6 = -2
Answer: (-5,-3)
Step-by-step explanation:
first you must know left and right is the x-axis while you and down is 4-axis, down and left is subtraction, right and up is addition
so 3 units left would affect x axis therefor subtracting 3 from -2 which is -5
now 5 units down would be the y-axis and subtracting, 2-5= -3
finally your answer will be (-5,-3)
