For the standardized test statistic approach to hypothesis testing, calculate the test statistic for testing the null hypothesis that the population mean is less than or equal to 9.94, given a sample mean of 15.20, a sample size of 49, and a population standard deviation of 3.25. Round to two decimals.
Homework Answers
Hence, the test statistic is 11.33.
Here we used z-statistics because population standard deviation is given.
I hope this will help. Thank you.
