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: easy it’s..........
Step-by-step explanation: 26+M
Answer:
It’s a bar graph because those orange rectangles show the data
The probability of the first one didn't do homework s 4/7,
the second is 3/6,
the third is 2/5,
Multiple all of them together
4/7*3/6*2/5=0.1143 or 11.43%
Answer:
0.1143 or 11.43%
The answer for a 15% discount would be 100%-15% or 85% of the original price, multiplied by 45, is $38.25
