Find the percent of women not experiencing any new UTIs in each of the three treatment groups.

American cranberry (Vaccinium macrocarpon) was used medicinally by Native Americans for the treatment of bladder and
kidney ailments.
A randomized controlled study was designed to test whether regular drinking of cranberry juice can prevent the recurrence of
urinary tract infections (UTIS) in women. 150 women with a urinary tract infection were treated with an antibiotic and then
randomly assigned to one of three groups. One group drank cranberry juice concentrate daily for six months; another group
took a drink containing Lactobacillus, a lactose-fermenting bacterium thought to help inhibit the growth of UTI-causing
bacteria, daily for six months; the last group served as the control group and drank neither cranberry juice nor Lactobacillus
drinks for six months.
After six months, the number of women in each group with recurring symptomatic urinary tract infection (defined as one or
more new infections) was recorded. The results are summarized in the table.

An article describes a study in which a new type of ointment was applied to forearms of volunteers to study the rates of absorption into the skin.

How many different choices were there for the six locations to apply the new ointment?
You are in charge of quality control for a company that manufactures a famous luxury brand ofhandbags. There are three different defects that you must be on the lookout for. A defect in any ofthese areas means the handbag cannot be sold and must be either recycled or destroyed.• Defects in stitching: 11% of items• Defects in coloring: 8% of items• Defects in materials: 4% of itemsBecause the areas (stitching, coloring/dying, materials) are done by different suppliers or in differentareas of the manufacturing plant, you may assume that the types of defects are independent of eachother.1. If there is a defect in all of the areas, the product must be destroyed. What percentage of bagswill need to be destroyed?2. A defect in coloring or materials means the product cannot be recycled and must therefore bedestroyed. For what percentage of bags will this be the case?3. What is the probability that a defect will be found of any of the three types?
Type O-negative blood type is called the universal donor type because it is compatible with any blood type. The American Red Cross reported that the proportion of O-negative blood type in the U.S. is about 7%. A physician assistant wishes to estimate the proportion, p, of individuals with an O- negative blood type. He conducts a survey and in a random sample of 300 records from a large hospital, 27 were found to have type O-negative blood type. The sample proportion is _____________. Give a 95% confidence interval for the proportion of O-negative blood type in this hospital. Interpret your interval with the context. Test if there is strong evidence that the proportion of O- negative blood type from a large hospital is different the national proportion. State your conclusion at 5% significance level. Which method will you use to perform the test? Choose the correct one. 1-sample T test 1-sample Z test 1-proportion Z test. 2-proportion Z test Which distribution will…

Alcohol abuse has been described by college presidents as the number one problem on campus, and it is an important cause of death in young adults. How common is it? A survey of 10,904 randomly selected U.S. college students collected information on drinking behavior and alcohol-related problems. The researchers defined “frequent binge drinking” as having five or more drinks in a row three or more times in the past two weeks. According to this definition, 2486 students were classified as frequent binge drinkers. Construct and interpret a 99% confidence interval for the proportion of students who are classified as binge drinkers. (Use the four-step process.) What would you include in "State" from the 4-step process?
Ride services are on the rise, such as Uber and Lyft. You wondered if the recent news reports of crime occurring with these ride services impacted the usage of them, especially with women. You decide to conduct a survey about ride service usage among male and female college students. The results showed that 19 males use ride services and 11 do not. While 12 females use ride services and 18 do not. Calculate the degrees of freedom:

We want to know if students with bronchitis at 5 years have more cough symptoms when they grow up. Out of 290 children with Bronchitis at Age 5, 32 of them has cough symptoms at Age 12.

A new screening test for Lyme disease is developed for use in the general population. The sensitivity and specificity of the new test are 60% and 70%, respectively. Three hundred people are screened at a clinic during the first year the new test is implemented. Assume the true prevalence of Lyme disease among clinic attendees is 10%. Calculate the number of false positives.
A substance abuse counselor wants to demonstrate the effect of situational stress on alcohol cravings. He recruits two groups of men who are similar in respect to history of alcohol use and demographic variables. He divides them in to two groups. In one group(n=11), the men are exposed to a stressful situation and then asked to complete a measure rating their alcohol cravings on a scale from 0-10, where 0 representsno cravings and 10 represents intense cravings. In the second group (n=10), the men are exposed to a neutral situation and asked to complete the same measure. What test and graph should I create to find out if a stressful situation result in more intense alcohol cravings than a non-stressful situation?
