The following results are from an independent-measures, two-factor study with n = 10 participants in each treatment condition. Factor A: Factor B: A₁ A₂ B₁ n = 10 M = 4 T = 40 SS = 50 n = 10 M = 5 T = 50 SS = 60 ΣΧ2 = 640 Factor B: B₂ n = 10 M = 1 T = 10 SS = 30 n = 10 M = 2 T = 20 SS = 40
As an occupational health epidemiologist you are required to measure the effect of stress on the workers in your manufacturing plant. Two different tests previously developed to measure stress in industrial workers are selected: stress test alpha and stress test delta. The sensitivity and specificity of each test are shown below. Which test generates the greatest proportion of false negatives? Stress Test Alpha Stress Test Delta Sensitivity = 60% 75% M Specificity = 95% 90% Stress Test Alpha Stress Test Delta
In an experiment on factors affecting tooth growth, 40 guinea pigs each received either 1 or 2 mg/day of vitamin C, delivered via orange juice (OJ) or an ascorbic acid pill (AA). The dependent variable was the length of odontoblasts (cells responsible for tooth growth). The descriptives are shown in the plot and table below. In a factorial ANOVA on odontoblast length, the F values for the main effect of dose, the main effect of delivery method, and the interaction were 31.35, 6.62, and 6.99, respectively. In simple effects analyses on the effect of delivery method, t was 4.03 when the dose was 1 mg/day, while t was .05 when the dose was 2 mg/day. 3. 30 - Method O OJ • AA 25 - Descriptives - Length 20 Dose Method Mean SD N 15 1 mg/day OJ 2 mg/day OJ AA 16.770 2.515 10 22.700 3.911 10 10 AA 26.140 4.798 10 1 mg/day 2 mg/day 26.060 2.655 10 Dose Report the full set of results in APA style, including degrees of freedom for all tests, the direction of all significant effects (a = .05), and…

Are seatbelts effective at saving lives? We wish to examine whether or not the use of seatbelts reduces fatalities at the a = 0.01 level of significance. Let pN represent the proportion of non-seatbelt wearing passengers who were involved in a crash and died and py represent the proportion of seatbelt wearing passengers who were involved in a crash and died. NOTE: The data used in this study were obtained through observational study...no experiment was conducted! Which would be correct hypotheses for this test? O Ho:PN = pY, H1:PN > pY Ho: PN = pY, H,:PN Py In a random sample of 321 non-seatbelt wearing passengers involved in a car crash, 30 were killed.
