A national park in Namibia determines the weight (in kg) of a sample of common eland antelopes:
450 730 700 600 620 660 850 520 490 670 700 820
910 770 760 620 550 520 590 490 620 660 940 790
a) the point estimate of µ and σ 2 and
b) the confidence interval for µ (α = 0.05).
under the assumption that the weight is normally distributed.
