1. Given the data set (10, 8, 6, 4, 7,5), what will be the z-score values when this is converted to a standard normal distribution? (Hint: use the population standard deviation).
O (1.69, 0.68, -0.34, -1.36, 0.17, -0.85)
O (3.33, 1.33,-0.67, -2.67, 0.33, -1.67)
O (11.09, 1.77, 0.45, 7.13, 0.11, 2.79)
