The mean height of the students in marta's class is 60 in. there are 18 students in her class. write and solve and equation to find the total measure of all student's heights. (hint, the mean is found by dividing the sum of all data values by the number of data values)

Max recorded the heights of 500 male humans. he found that the heights were normally distributed around a mean of 177 centimeters. which statements about max’s data must be true? a) the median of max’s data is 250 b) more than half of the data points max recorded were 177 centimeters. c) a data point chosen at random is as likely to be above the mean as it is to be below the mean. d) every height within three standard deviations of the mean is equally likely to be chosen if a data point is selected at random.
