Answer:
LCL = 59.26 to two decimal places
Step-by-step explanation:
Here, we want to estimate the LCL of the population mean with 90% confidence
We proceed as follows;
Given alpha = 0.1, then Z(0.05)=1.645 (from standard normal table), s = 15
Mathematically;
LCL =x_bar -Z*s/√( n)= 62 - (1.645 * 15)/√81
LCL = 62- (24.675)/9 = 59.2583
LCL = 59.26 to two decimal places
Plug in the given values and you'll see its option 2.
x=0 , f(x) = 0^2 + 1 = 1
x = 1 , f(x) = 1^2 + 1 = 2
x = 2, f(x) = 2^2 + 1 = 5
