of times that adults go for a walk each week is less than 2.0. I spoke with 8 adults and found that they went on walks 3,5,2,1,0,4,0 and 5 t
I believe that the population mean number of times that adults go for a walk each week is less than 2.0. I spoke with 8 adults and found that they went on walks 3,5,2,1,0,4,0 and 5 times last week. Test this hypothesis at the 0.5 significance level.
Let X be the random variable such that the number of times that adults go for a walk each week.
The given sample is
3,5,2,1,0,4,0 and 5
: Sample mean a number of times that adults go for a walk each week.
s: Sample standard deviation number of times that adults go for a walk each week.
n: Sample size = 8
It is required to test whether the population mean number of times that adults go for a walk each week is less than 2.0.
Calculating the sample statistic first.
Sample mean:
=
= 2.5
Sample standard deviation:
= 2.070197
