The following are the closing prices of some securities that a mutual fund holds on a certain day:

10.25	5.31	11.25	13.13	18.00	32.56	37.06	39.00
43.25	45.00	40.06	28.56	22.75	51.50	47.00	53.50
32.00	25.44	22.50	30.00	24.75	53.37	51.38	26.00
53.50	29.87	32.00	28.87	42.19	37.50	30.44	41.37

(a) Find the mean, variance, and range for these data and interpret.

(b) Find lower and upper quartiles, median, and interquartile range. Check for any outliers.

(c) Construct a box plot and interpret.

(d) Construct a histogram.

(e) Locate on your histogram x, x ± s, x ± 2s, and x ± 3s. Count the data points in each of the intervals x± s, x ± 2s, and x ± 3s and compare this with the empirical rule.
