A handsoap manufacturer introduced a new liquid, lotion enriched, antibacterial soapand conducted an extensive consumer survey to help judge the success of the newproduct. The survey showed 40% of the consumers had seen an advertisement for thenew soap, 20% had tried the new soap, and 15% had both seen the advertisement andtried the new soap. If a randomly selected consumer has seen the advertisement for thenew soap, what is the probability that this consumer has tried the new soapa. 72%C. 40%b. 25%d. 37.5%

As a warehouse manager, it is your responsibility to inspect a large shipment of components for defects. Two independent random samples, each of size 20 of these components will be checked, and the shipment will be accepted if fewer than 3 of these components are defective in both samples. What is the probability of accepting a shipment containing 10% defectives?
To avoid being stuck with a shipment of defective HDTV sets, a large retailer tests a random sample of three televisions for defects before purchasing the entire shipment. If any of the three HDTV sets are defective, the entire shipment is rejected. If a manufacturer of HDTV sets has a 1.2% defect rate, what is the probability that a shipment of its HDTV sets will be rejected by this retailer?
The M&M/Mars candy company does a lot of market research to determine the most appealing mix of colors in M&M candies. Recently, one mix was: Purple 20%; Yellow 20%; Red 20%; Orange 10%; Green 10%; Blue 10% and Brown 10%. Suppose you reach into a bag of M&M candies and draw out ONE candy at random. What is the likelihood of drawing a Purple candy?
Dr. Sloane is doing a study to test the association between alcohol consumption and the occurrence of cancer of the liver. He chooses a hospital-based sample and collects all newly diagnosed cases of histologically confirmed liver cancer diagnosed at that hospital. For his control group, he reviews the charts of all patients coming through all the clinics at this hospital who are not diagnosed with liver cancer. He makes sure that the cases and controls are similar by age and sex. A. Looking at the odds ratios and the p-values together, describe your observations. B. Looking at the p-values, what do they tell you about the strength of the association between drinking different amounts of alcohol per day and the risk of having liver cancer?
A small business is studying the number of customers that enter the store. They record the number of customers entering every hour for three days, and find that 27% of the time two customers enter the store in an hour, 28% of the time of the time one customer enters the store in an hour, and the remainder of the time no one enters the store in an hour. What is the expected number of customers per hour?

A dowser has correctly located water for a well 1 out of 2 times in Jones County. In Jones County, someone who is just guessing has a 40% chance of locating water for a well. Does this sample provide sufficient evidence that the dowser can locate water and is not just guessing?
A pharmaceutical company receives large shipments of aspirin tablets. The acceptance sampling plan is to randomly select and test 47 tablets, then accept the whole batch if there is only one or none that doesn't meet the required specifications. If one shipment of 6000 aspirin tablets actually has a 3% rate of defects, what is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will be accepted is (Round to four decimal places as needed.)
The use of a HPV vaccination is effective at decreasing risk of cervical cancer overall. Investigators wished to study whether there is a difference in cervical cancer risk among three different risk categories: monogamous relationships only, casual sexual relationships, and anonymous sexual relationships. The investigators then kept track of how many women developed cervical cancer in the study. The expected % of cervical cancer in each of the three risk factor groups is provided. You are interested in investigating if there is a difference between the expected and the observed percentage of women that developed cervical cancer in the three risk categories. What kind of sample and outcome is this?
