Determine (a) the mean, (b) median, (c) mode, (d) range, (e) standard deviation, (f) variance, and (g) coefficient of variation.

(h) Construct a histogram. Use a range from 26 to 32 with increments of 0.5.

(i) Assuming that the distribution is normal, and that your estimate of the standard deviation is valid, compute the range (that is, the lower and the upper values) that en­compasses 68% of the readings. Determine whether this is a valid estimate for the data in this problem.
