Question
The population mean of the heights of five-year old boys is 100cm. A teacher measures the height of her twenty five students, obtaining a mean height of 105cm and standard deviation 18. With a 5% significance level to calculate whether the true mean is actually greater than 100cm.
What is the test statistic and p-value
O z=1.39. p-0.824
O t=1.39, p-value-0.0888
O t-1.39. p-value=0.0888
O z=-1.39. p=0.824
