Suppose that a software development team released an update to one of their mobile applications after receiving complaints
about the previous version from 10.6% of their customers. A few weeks after the update was released, the development team
wanted to know if fewer customers had complaints. The team selected a random sample of 350 customers and found that 22
of them submitted complaints about the application after the update was released.
The team wants to use a one-sample z-test for a population proportion to see if the proportion of customers with complaints,
p, has decreased since they released the update. For this test, they plan to use a significance level of a = 0.01.

1. an economy consists of three workers: larry, moe, and curly. each works 10 hours a day and can produce two services: mowing lawns and washing cars. in an hour, larry can either mow one lawn or wash one car; moe can either mow one lawn or wash two cars; and curly can either mow two lawns or wash one car. a. calculate how much of each service is produced under the following circumstances: a. all three spend all their time mowing lawns. b. all three spend all their time washing cars. c. all three spend half their time on each activity d. larry spends half of his time on each activity, while moe only washes cars and curly only mows lawns b. using your answers to part a, draw a production possibilities frontier and label points a, b, c, and d on your graph. explain why the production possibilities frontier has the shape it does. c. are any of the allocations calculated in part a inefficient? explain.
