Pz 15 points describe the center and spread of the number of chin-ups done by students in the 4th period class using either the mean and standard deviation or the five-number summary. justify your choice using the histogram. round to the nearest tenth if necessary.
the distribution is symmetric, so use the mean and standard deviation.
mean: 9.1, standard deviation: 4.1
the distribution is skewed, so use the five-number summary.
range: 15, median: 9.5, half of the data are between 6.5 and 12
