The information on an antibiotic and bacterial-culture usage in hospitals for patients who were discharged from two selected Pennsylvania hospitals were collected. Among the sampled 25 patients from Hospital 1, 7 patients received anti-biotics. And from Hospital 2, 6 patients from the sampled 30 patients received bacterial culture. Investigators are interested in assessing whether the proportions for patients receiving an antibiotic is greater than the proportion of receiving a bacterial culture while in the hospital at α=0.05.

What is the test statistic? Report your answer up to 3 decimal places.

1.Water samples were taken from water used for cooling as it was being discharged from a power plant into a river. It has been determined that as long as the mean temperature of the discharged water is at most 150 F, there will be no negative impact on the river's ecosystem. To investigate whether a plant is in compliance with regulations that prohibit a mean discharge water temperature above 150 F, researchers took 50 water samples at randomly selected times...
