1) Suppose you are a 20 year old student and you have convinced your parents to let
you live off campus. Remarkably, they have agreed to pay for your housing.
Suppose your parents claim that one-bedroom apartments cost an average of $600
per month. You disagree, and think one-bedroom apartments are more expensive
than that. Suppose you went to the local paper and found 40 one-bedroom
apartments listed. You calculate a sample mean of x = $600 with a standard
deviation of ơ = $50. You and your parents have agreed on the a = .05level.
a)
State the null and alternative hypotheses.
What is the critical value? Sketch a density curve and identify the
b)
critical region.
