I am unsure where to begin on this problem and what formulas to use.
here is the problem:
the chamber of commerce of clarkston, wa was interested in trade dollar loss to its twin city, lewiston, ID. the chmaber had been concerned that over a period of years, average household expenditures across the state line were too high and detrimental to commercial growth. the chamber thus develop a "spend at home" program. Researchers surveyed clarskton households to estimate household expenditures across the state line after the "spend at home" program. A randon sample of n=100 households was surveyed. the following are summary and results of the survey:
average yearly expenditures X:$3600 with a standard deviation theses expenditures of S=$1000.
the average household dollars the chamber expected to give lewiston in the absence of the sepnd at home program was mean= > or equal to $3800.
at a=.05. conduct the test of your null hypotheses. accept or reject? type I or type II error?
PLease help me get started in the right direction.
