Which study will result in the smallest p-value (you do not have to calculate the p-value for each option to figure this out)? Standard deviation = 10, sample size = 2, population mean = 65, sample mean = 60 Standard deviation = 10, sample size = 5, population mean = 75, sample mean = 70 Standard deviation = 10 sample size = 12, population mean = 80, sample mean = 75 Standard deviation = 10, sample size = 20, population mean = 55, sample mean = 50
