The board of real estate developers claims that 55% of voters will vote for a bond issue to
fund the construction of a new water tower. A random sample of 215 voters was taken
and 106 would vote for the new water tower project. Does this indicate that the percent
of voters who favor such a project is different?
What is the null and alternate hypotheses you would use for this statistical study?
p=.55 and p<.55
P=.55 and p does not equal.55
P=.49 and p does not equal.55
P=.55 and p>.55

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i.e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
