Question 1192085: The contents of 33 cans of Coke have a sample mean of x =12.15 and a standard deviation of s=0.11. Find the value of the test statistic t for the claim that the population mean is μ=12. Answer by Theo(13342) (Show Source):
You can put this solution on YOUR website! n = 33
sample mean = 12.15
sample standard deviation = .11
claim is population mean is 12
standard error = sample standard deviation / square root of sample size = .11/sqrt(33) = .01915.
t-score = (x - m) / s = (sample mean minus assumed mean) / standard error = (12.15 - 12) / .01915 = 7.83.
that would be the test statistic.
