A panel of dentists is interested in testing two different toothpaste brands (A and B) to see if there is a relationship between the brand and whether or not the patient has a cavity at their next appointment. A representative sample of 60 patients is recruited to take part in this study. At their first appointment of the year, each subject is assigned to brush their teeth with one of the two brands for the next six months. At their follow-up appointment six months later, they were checked for cavities. ******In the sample, 6 of the 30 patients assigned to Brand A were found to have a cavity. The fraction 6/30 should be denoted by which of the following? μ x̄ p p̂ n s σ χ²

A student researcher was surprised to learn that the 2017 NCAA Student-Athlete Substance Use Survey supported that college athletes make healthier decisions in many areas than their peers in the general student body. He collected data of his own, focusing exclusively on male student-athletes to see if such habits vary based on one’s sport. He asked 93 male student-athletes whether they had engaged in binge-drinking in the last month (> 5 drinks in a single sitting).

A manager at a local discount gym believes that less than 20% of gym members use the gym, at least 5 days a week. She randomly selects 100 gym members and tracks (using the electronic login system at the door) how many days they used the gym over the 2-week period. The following are the results: 2 3 10 4 2 3 8 4 8 10 5 0 6 3 9 13 6 3 12 5 3 3 5 1 5 9 8 5 8 2 6 4 4 2 12 1 3 3 2 12 7 3 14 2 8 5 2 6 1 5 6 9 6 8 10 1 11 3 2 1 5 4 1 2 3 13 7 4 8 3 7 4 3 2 10 3 1 7 11 8 4 7 6 7 8 11 7 6 3 2 5 0 4 6 5 12 2 10 1 2 Test the manager's claim at the 2.5% level of significance.

Trematodes of the species Euhaplorchis californiensis may infect the California kill fish, Fundulus parvipinnis. Researchers have observed that infected fish spend excessive time near the water surface, where they may be more vulnerable to bird predation. Researchers set up an experiment in a large outdoor tank that stocked with three kinds of killifish, uninfected, lightly infected, and highly infected, and recorded the number of fish that is eaten by birds. State the null and alternative hypothesis
A scientist is interested in whether stretching before running 5 kilometers will improve a runner’s time. The scientist decides that an experimental study is the best method to use to answer the question. One group of runners will run a 5-kilometer race without stretching, and a second group of runners will follow a specific stretching routine before running the race. The finishing times will be recorded, along with the group type for each runner. Assuming this group is representative of all adults who followed a specific stretching routine before running, use a normal distribution to estimate the probability that a randomly-selected adult could complete the race in fewer than 20 minutes after stretching. **THIS IS THE FULL QUESTION AND THIS IS NOT GRADED ***
Exercises 5–8 refer to the study of an association between which ear is used for cell phone calls and whether the subject is left-handed or right-handed. The study is reported in “Hemispheric Dominance and Cell Phone Use,” by Seidman et al., JAMA Otolaryngology—Head & Neck Surgery, Vol. 139, No. 5. The study began with a survey e-mailed to 5000 people belonging to an otology online group, and 717 surveys were returned. (Otology relates to the ear and hearing.) Response Rate What percentage of the 5000 surveys were returned? Does that response rate appear to be low? In general, what is a problem with a very low response rate?

A school Psychologist is interested in the effect of violent television programs on a child's agression depending on if the show is a cartoon or not. Eighty children were recruited and were divided into equal groups. Half of the children watched a violent television program while the other half watched a non- violent program. Half of the children watched a cartoon while the other half watched a show that was not a cartoon. The children were then placed in a small group and the researcher measured the level of agressiveness of each child.

A company produces mood music, and wants to study the music and whther it substantially helps peoples mood. the first intern decides to survey adults, asking them if they are feeling cheerful at the moment. 280 adults who do not listen to the mood music are asked if they are feeling cheerful at the moment. 112 say they are. the intern then asks 172 adults who listen to mood music regurlarly of they are feeling cheerful: 87 say they are. The intern will only claim that the music enhances peoples mood if he can state with 95% certainty that the % of adult mood music listeners who feel cherful beats thes rest of the adult population more than 4% e) based on this survey, can the intern make the claim that the music improves peoples mood f) generate a 95% confidence interval regarding the differnce between the % of adults who listen to mood music who feel cheerful and the % of adults who dont listen to mood music who feel cheerful round to the nearest 1%
