using an organic corn fertilizer:

212, 234, 259, 189, 245, 176, 203, 215

(a) For this sample of n = 8 observations, use R to obtain the mean, the median, the interquartile range and the standard deviation.

(b) Among the four statistics, which are measures of central tendency and which are measures of dispersion.

(d) With R, produce a quantile-quantile plot for these data. Is it reasonable to assume that the weight is normally distributed? Explain.

(e) Give a point estimate for the mean weight of the population and the standard error of the estimate.
