Step-by-step explanation:
Information given
represent the mean height for the sample
represent the sample standard deviation
sample size
represent the value that we want to test
t would represent the statistic
represent the p value for the test
Hypothesis to verify
We want to cehck if the true mean is lees than 25 mph, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic would be given by:
(1)
Replacing the info given we got:

Answer:
Step-by-step explanation:
The body of the Cylinder.
Formula
Area of the body = circumference * length
circumference = 2*pi * r
r = 6 m
Circumference = 2 * 3.14 * 6
Circumference = 12 * pi
Area of body = 12*pi * length
area of body = 12*9 * pi
Area of body = 108* pi
Two ends
The diagram is not complete enough to know whether or not there are 2 ends or one. I'll assume 2.
Area = 2 * pi r^2 For both
Area = 2 * pi * 6^2
Area = 72 pi
Total Area
Total area = 72 pi +108 pi
Total area = 180 pi
Total Area = 180 * 3.14
Total Area = 565.2
