Suppose that you want to conduct a right tailed hypothesis test for the population mean (o unknown). With a random sample of size 15, you calculate the value of the test statistic tcalc as 0.78. What is the p-value for the hypothesis test? Hint: you may use the Excel function to obtain the p- value as showed in the video lecture notes. Select one: 0.2242 0.4484 0.2238 0.4475
