Scientific research on popular beverages consisted of 65 studies that were fully sponsored by the food industry, and 35 studies that were conducted with nocorporate ties. Of those that were fully sponsored by the food industry, 14 % of the participants found the products unfavorable, 24 % were neutral, and 62% found the products favorable. Of those that had no industry funding, 40 % found the products unfavorable, 18 % were neutral, and 42 % found theproducts favorable.What is the probability that a participant selected at random found the products favorable?4If a randomly selected participant found the product favorable, what is the probability that the study was sponsored by the food industry?If a randomly selected participant found the product unfavorable, what is the probability that the study had no industry funding?

2. An article in the journal Applied Nutritional Investigation reported the results of a comparison of two different weight-loss programs (Liao, 2007). In the study, obese participants were randomly assigned to one of two groups and the percent of body fat loss was recorded. The soy group, a low-calorie group that ate only soy-based proteins (M= 3.1, s=0.55), while the traditional group, a low-calorie group that received 2/3 of their protein from animal products and 1/3 from plant products (M= 1.9, s=0.45). If sm1-M2 = 0.24, s²pooled = 0.25, n1 = 8, n2 = 10 is there a difference between the two diets. Use alpha of .05 and a two-tailed test to complete the 4 steps of hypothesis testing.
The U.S. Department of Transportation reported that during November, 83.4% of Southwest Airlines' flights, 75.1% of US Airways' flights, and 70.1% of JetBlue's flights arrived on time (USA Today, January 4, 2007). Assume that this on-time performance is applicable for flights arriving at concourse A of the Rochester International Airport, and that 40% of the arrivals at concourse Aare Southwest Airlines flights, 35% are US Airways flights, and 25% are jetBlue flights. a) Deveiop a joint probability table with three rows (airlines) and two

A survey of 2645 consumers by DDB Needham Worldwide of Chicago for public relations agency Porter/Novelli showed that how a company handles a crisis when at fault is one of the top influences in consumer buying decisions,with 73% claiming it is an influence. Quality of product was the number one influence, with 96% of consumers stating that quality influences their buying decisions. How a company handles complaints was number two, with 85% of consumers reporting it as an influence in their buying decisions. Suppose a random sample of 1,200 consumers is taken and each is asked which of these three factors influence their buying decisions. Appendix A Statistical Tables a. What is the probability that more than 910 consumers claim that how a company handles a crisis when at fault is an influence in their buying decisions?b. What is the probability that fewer than 1,125 consumers claim that quality of product is an influence in their buying decisions?c. What is the probability that between…
A clinical psychologist is interested in determining which type of therapy is in fact more effective at treating depression. The psychologist randomly assigns 1/3rd of the participants to receive cognitive behavioral therapy, 1/3rd to receive the psychodynamic therapy and 1/3rd to receive humanistic therapy. Following the therapy sessions, the psychologist gives the members of each group the Beck Depression Inventory and compares the scores of the three groups. 1 What hypothesis test would be most appropriate for answering this research question and why? 2 If the researcher found that at least one of groups differed, what type of follow-up test would be most appropriate? 3 What are the independent and dependent variables (if any)?
A study classified each of 134 lawyers into one of four groups based on observation and an interview. The 62 lawyers in group A were categorized as having high levels of stimulation and support and average levels of public spirit. The 52 lawyers in group B had low stimulation, average support, and high public spirit. Group C contained 7 lawyers with average stimulation, low support, and low public spirit. The 13 lawyers in group D were assessed as low on all three criteria. Salary levels for these four groups were compared. The sample means were 7.87 for group A, 7.47 for group B, 5.14 for group C, and 3.69 for group D. The F ratio calculated from these data was 25.60. a. Prepare the complete analysis of variance table. b. Test the null hypothesis that the population mean salaries are the same for lawyers in these four groups.
A research wants to determine if pre-natal exposure to the hormones in birth control pills alters the sex makeup of midshipman fish populations (which are typically half male and half female).Specifically, the researcher wishes to test the hypothesis that exposure to hormones will increase the number of females in the population.The researcher exposes a group of pregnant midshipman fish to birth control hormones and records the sex of the first 13 offspring birthed.They then observe that 11 are female.Use a sign test and a alpha of .05 to test the indicated hypothesis.What is the critical value?
In a clinical experiment, people newly diagnosed with depression were randomly placed into two treatment groups: group A only took medication to treat depression and group B took medication and also underwent counseling. They then tracked their progress and grouped results into two categories after one year of treatment: "good outcome" and "poor outcome" based on improvement from initial diagnosis. The results of this study are represented by the following contingency table: poor outcome good outcome medication & counseling medication only 24 276 42 258 Perform a relative risk analysis on this dataset. What is the relative risk score? (include three significant digits; e.g. 0.001)
Researchers were interested in how social situations can influence stress-induced eating. They grouped participants according to self-reported stress-induced eating habits: consistently eating more (hyperphagics) or eating less (hypophagics) when stressed. Each participant was then exposed to one of three social situations: (1) a social inclusion condition, where subjects were told that a confederate partner had approved of a video they had made answering some questions and was looking forward to meeting them, (2) a neutral condition, where they were told their partners could not meet them because their partners had to cancel their participation, or (3) a social exclusion condition, where they were told that their partner had decided not to meet them after viewing their video. Subjects were then given an ice cream taste test and the amount of ice cream consumed was measured. Question: How many factors are in this scenario?
