The true mean number of siblings my Facebook friends have is X=2.9
My estimated sample mean was X=3
The margin of error:
T-(s/√n) =1.96(1.5/√40) = 5 Siblings
Confidence Interval:
√ 2.9+5= (2.4,3.4)
Conclusion I am 95% confident that 40 of my Facebook friends have
between 2.4 and 3.4 siblings.

Critical Value:
At the .05 level of significance, my critical values are + 1.96
P-Value*: P(Z - 42)+P(z>-42)=3372+.3372-6744
Decision Because my test statistics is -42 is less than 1.96 and because
my P-Value of 6744 is not significant at p= .05
