Step-by-step explanation:
Answer: (1.375, 18.625 )
Step-by-step explanation:
The confidence interval for population mean is given by :-
(1)
, where = sample mean
t* = critical value.
SE = standard error
As per given , we have
n= 21
Degree of freedom : df = n-1=21-1=20
Significance level :
Standard error : SE= 5
The critical t-value for confidence interval is a two-tailed value with respect to the given degree of freedom i.e. .
Using student's t-distribution table ,
The 90% confidence interval will be :
[by formula in (1)]
Hence, the limits of the confidence interval=(1.375, 18.625 )
Answer:
1482 feet squared
Step-by-step explanation:
I think it is 1482.
First...
Find the total area if this was a rectangle.
46*37 = 1702
Next...
Find the area of the patio and garden.
Patio: 10*16 = 160
Garden: 12*5 = 60
Then...
Add them.
Patio + garden = 160 + 60 = 220
Finally...
Subtract 220 from 1702.
1702 - 220 = 1482
So your answer is 1482.
