The number of mosquitoes in Minneapolis, Minnesota (in millions of mosquitoes) as a function of rainfall
(in centimeters) is modeled by:
m(x)=-(x – 5)² + 25
How many centimeters of rainfall will produce the maximum number of mosquitoes?

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
