We select a random sample of ten oranges from trees grown in a
large orchard. The
standard deviation of weights of these ten oranges is calculated to
be 19 grams.
Based on this sample, a condence interval for the true mean weight
of all oranges
grown in the orchard is calculated to be (126:41; 153:59). What is
the condence
level of this interval?

A machine fills boxes of cereal in a factory. The average weight of cereal in a random sample of 17 boxes is calculated to be 350 grams and the sample standard deviation is calculated to be 8 grams. Weights of cereal per box are known to follow a normal distribution. We calculate a 90% confidence interval for the true mean weight of cereal per box. The margin of error for the appropriate confidence interval is:
