first please, to start with be to draw the normal curve in the standard deviation just to get an idea of what's going on with your data. So the mean of your data is 50. You have a standard deviation of eight, meaning that you will add eat, going to the rate to get 50 eat 66 and 74 going to the left. You'll subtract 83 times to get 42 34 and 26. No, the question is asking by the percent of data that is less than 50. So here's 50 so we want to know what percent it's below the mean basically. And if you have a reference table or a picture from your textbook, you'll know that half of the data, or 50% of the data, lies below the mean so 50% is your answer.
