A company produces 2 types of hats. Each hat of the I type requires twice as much as labour time as the II type. The company can produce a total of 500 hats a day. The market limits daily sales of I and II types to 150 and 250 hats. Assuming that the profit per hat are Rs.8 for type A and Rs. 5 for type B. Formulate amodels in order to determine the number of hats to be produced of each type so as to maximize the profit

Answer:
random sample from a population. Before performing a statistical inference, what should you do?
b) The following data displays the budgets, in dollars, of 45 randomly sampled home improvement jobs in the United States.

i. Obtain a 95% confidence interval for the population mean budget, μ, for such home improvement jobs and interpret your result in words. Assume that the population standard deviation of budgets for home improvement jobs is $1350.
ii. How would you decide whether budgets for such home improvement jobs are approximately normally distributed?
iii. Must the budgets for such home improvement jobs be exactly normally distributed for the confidence interval that you obtained in part (i) to be approximately correct? Explain your answer.
