A consumer products company is formulating a new shampoo and is interested in foam height (in millimeters). Foam height is approximately normally distributed and has a standard deviation of 20 millimeters. The company wished to test Ho: μ = 175 against H₁:μ> 175 millimeters, using the results of n = 10 samples. If the sample data result in x = 190 millimeters, find the value for the test statistic zo.
