Answer: (97.084, 99.116)
Step-by-step explanation:
As per given , we have
sample size :n= 106
degree of freedom: df = 105 (df=n-1)
Significance interval :
Since , population standard deviation is unknown , so we use t-test .
Using t-value table ,
Now , 80% Confidence interval will be :
Thus , The 80% confidence interval estimate of the standard deviation of body temperature of all healthy humans = (97.084, 99.116).
I’m sure it’s the last one D
SOLUTION:
= ( 7 / 8 )m + 9 / 10 - 2m - 3 / 5
= - ( 9 / 8 )m + 3 / 10
8-2-2=4 or 8-4=4 hope this helps
Length = 7 Width = 2
Step-by-step explanation:
L = Length
W = Width
L=9w-11
2L+2W=18
2(9W-11) + 2W = 18
18W - 22 +2W = 18
20W -22 = 18
20W = 40
W = 2
L = 9(2)-11
L=18-11
L=7
