The weights in pounds of a breed of yearling cattle follows the
Normal model
N(1128,62).
What weight would be considered unusually low for such an
animal?
Select the correct choice below and fill in the answer boxes
within your choice.
A.Any weight more than 2 standard deviations below the mean, or
less than
nothing
pounds, is unusually low. One would expect to see a steer 3
standard deviations below the mean, or less than
nothing
pounds only rarely.
B.Any weight...

To determine the weight of plastic discarded by households, a
sample size of 62 weights are measured and are found to have a mean
of 1.911 lb and a standard deviation of 1.065 lb. Construct a 99%
confidence interval estimate of the mean weight of plastic
discarded by all households.
