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:
28 inch
Step-by-step explanation:
The length of all four sides of square is equal.
The formula used for finding the area of square is:
Area = (Length) × (Length)
Thus, the Area of square whose length is 2√7 is:
Area = 2√7 × 2√7
⇒ Area = 4 × 7 = 28 inch.
