A scientist cоnducts аn experiment tо determine if the meаn аlkalinity level оf water specimens from the Olentangy River is greater than 50 milligrams per liter (mpl). She selects a random sample of 100 water specimens from the river and finds a sample mean of 67.8 mpl and a sample standard deviation of 14.4 mpl. She decides to test the hypothesis using a significance level of 0.01. Using this information, calculate the value of the test statistic.
