If there are 140 in a class who have taken a test with a mean of 64 and a SD of 6, how many students scored between 58 and 70? Hint: Determine whether the lower boundary of the range is the mean or below the mean. Then, determine how many standard deviations (jumps from the mean in either direction) are needed to fill the range. Then add the percentages under the curve between the lower and upper boundary. Then change the percentage into a decimal by moving decimal point two places to the left. Finally multiply the decimal by the number of people in the class. Remember to round up or down as there can never be a fraction of a student. O 95 96 None of the answers listed 100 68
