General health guidelines state that the mean daily calorie intake for active teenage boys (aged between 14 - 18 years of age) should not exceed 3,400 calories. In a study of dietary intake, a sample of 14 - 18 year old boys was found to have a mean daily calorie intake of 3,975. Suppose that this result was based on a sample of size 105 and that the population standard deviation is 1,450 calories. The researchers were interested in determining whether the mean daily calorie intake for teenage boys exceeded the maximum recommended level. Let μμ represent the true mean sodium intake for all teenage boys (aged between 14 - 18 years of age). Then, H0: μμ < 3,400 versus Ha: μμ > 3,400 What is the value of the test statistic?
