Suppose babies born in a large hospital have a mean weight of 4088 grams, and a variance of 55,696.

If 128 babies are sampled at random from the hospital, what is the probability that the mean weight of the sample babies would be less than 4132 grams? Round your answer to four decimal places.

Suppose that a paving company produces paved parking spaces (q) using a fixed quantity of land (t) and variable quantities of cement (c) and labor (l). the firm is currently paving 1,000 parking spaces. the firm's cost of cement is $3 comma 600.003,600.00 per acre covered (c) and its cost of labor is $35.0035.00/hour (w). for the quantities of c and l that the firm has chosen, mp subscript upper c baseline equals 60mpc=60 and mp subscript upper l baseline equals 7mpl=7. is this firm minimizing its cost of producing parking spaces?
