If a population has a mean of 75 and has a standard deviation of 14 find the percentages of the population that are less than 70 greater than 95 between 60 and 80
Added by Timothy M.
Step 1
For x = 70: z = (70 - 75) / 14 = -0.357 For x = 95: z = (95 - 75) / 14 = 1.429 For x = 60: z = (60 - 75) / 14 = -1.071 For x = 80: z = (80 - 75) / 14 = 0.357 Show more…
