Researchers conducted a medical study to find out if treating a sinus infection with an antibiotic reduced the length of the sinus infection. The study included 241 patients who were diagnosed with a sinus infection. There were 113 patients randomly assigned to receive the antibiotic. The remaining patients received sugar pills. The patients were contacted regularly to find out when each patient stopped having sinus infection symptoms. The results of the study are presented in the table below. TREATMENT Length...

In studies for a​ medication, 8 percent of patients gained weight as a side effect. Suppose 498 patients are randomly selected. Use the normal approximation to the binomial to approximate the probability that ​(a) exactly 40 patients will gain weight as a side effect. ​(b) no more than 40 patients will gain weight as a side effect. ​(c) at least 50 patients will gain weight as a side effect. What does this result​ suggest?

1.) Suppose a certain species of bacteria causes a skin infection and the treatment is a specific antibiotic. If the treatment is delayed and the bacteria are allowed to replicate, describe the processes that occur to cause the population of bacteria in the wound to become genetically diverse and possibly difficult to treat. Spring has sprung, and so have the dandelions. The dandelions are sprayed with an herbicide, but some dandelions survive. 2. Explain why a few of the dandelions...
