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
Answer:
False.
Step-by-step explanation:
If they have the same slope and same intercept they will have the same line. So they will have infinite solutions.
W=8
k=2
-9(-3k+6w)
-9(-3(2)+6(8)
-9(-6+48)
-9(42)
-378
The answer is -378
Answer:
your answer is .945 because you divide 7.37 by 7.80
