Determine whether the statement is true or false. If the statement is false, make the necessary change(s) fo produce a true statement. When finding the mean, it is necessary to arrange the data items in order. Choose the correct answer below. A. The statement is true. B. The statement is false. To make the statement true, change "mean" to "median", C. The statement is false. To make the statement true, change "mean" to "mode", D. The statement is false. To make the statement true, change "mean" to "median" and add "not" between "is" and "necessary",

Based on a sample of 70 people, the sample mean GPA was 3.43 with a standard deviation of 0.03 The p-value is: \( \square \) (to 2 decimals)
