An engineer measures the weights (in kilograms) of steel pieces.
They would like to
test H0 : = 5 against H1 : > 5. The weight of a steel piece is
normally distributed.
They select a random sample size of n = 25 steel pieces, and
compute x = 6:7 and
s = 2:37. We cannot conclude that the mean weight is larger than 5
kg at a level of
significance of 1%.
