Answer:
Z Test = -3.87298
p= .0001
Then the results are significant at p values < 0.1
Step-by-step explanation:
To answer this question we have to consider some things.
1) The Mean of Population is given by this formula:
The Population Standard Deviation is given by this formula:
On the other hand, the Team buddies are a <u>sample</u> of this population, whose mean is:
The Sample Standard Deviation is given by this formula:
The Z test shows us the validity of the results.
2)
For the Z test we need the Variance
Z = (M - μ) / √(σ2 / n)
3)
Z Test = -3.87298 standard deviation units, since it's a negative value is 3.897 below the mean.
p= .0001 the p value.
Then the results are <u>significant</u> at p values < 0.1
