Answer: (1.4964, 1.5126)
Step-by-step explanation:
We know that the confidence interval for population mean is given by :-
, where 
= population standard deviation.
n= sample size
= Sample mean
As per given , we have
σ = 0.01 inches
n= 10
Also, the critical value for 99% confidence interval = 
[From x-value table.]
[Significance level =1-0.99=0.01 and 
is 2.576.]
Then, the 99% two-sided confidence interval on the mean hole diameter will be :-
Hence, the required confidence interval = (1.4964, 1.5126)

Step-by-step explanation:
Cherry juice=5+5+5+5+5+5=30
Lime juice =3+3=6
6 cherry slushes and 2 lime slushes were sold.
Hope this helps!!
Let the missing number be x
Mean is the total sum of data over the number of data therefore,
(11+20+x+3+1) / 5 = 9
Then simplify
(35 + x) / 5 = 9
Then multiply 5 to both sides
35 + x = 45
Then subtract 35 to both sides to find x
X= 10
Hope this helps!
Answer:
235
Step-by-step explanation:
first, separate the floor into 3 different rectangles to calculate the area and then add them together.
area of rec=L*B
rec 1: 9*12.5=112.5
rec 2: (13.5-5.5)*(19.5-9-7)=28
rec 3:7*13.5=94.5
Then:
112.5+28+94.5=235
Gain - loss = profit
55- 45 = $10 net profit
