Answer: One sample z test for means
Step-by-step explanation:
From the information given, the sample size is large. It is greater than 30. Again, the population standard deviation is given. This means that the test statistic would be the z score which is determined by the formula
z = (x - µ)/σ
Where
x = sample mean
µ = population mean
σ = population standard deviation
The probability value would be determined from the normal distribution table.
Therefore, the hypothesis test that should be used is
One sample z test for means
Brett ran 9 1/2 miles or 9.5 miles
Adam ran 5.75 miles
9.5 - 5.75 = 3.75
Brett ran 3.75 miles more than Adam
the upside down T is always perpendicular so the answer is b. :)
