Answer:
62.8318530718 inches^3
Step-by-step explanation:
The volume of a cylinder can be found using:
V=πr^2h
Substitute 2 in for r (radius), and 5 in for h (height)
V=π2^2*5
V=π4*5
V=π20
V=62.8318530718
62.8318530718 inches^3

Answer:
Step-by-step explanation:
Given that the difference of sample means of two populations is 108.7, and the standard deviation of the difference in sample means is 32.
H0: difference inmeans =0
Ha: difference inmeans not equal to 0
(Two tailed test)
Test statistic = mean difference/std deviation
For 68% confidence level, }z}<1
Here z =3.40 >1
Hence reject null hypothesis
The difference between the means cannot be 0 and there is statistical evidence at 68% level to reject null hypothesis
Answer:
25
Step-by-step explanation:
144/60 = 2.4
60/2.4 = x
