Compute a posterior probability of you having the COVID-19, i.e., P(COVID|+), given that you tested + to the antibody test. Assume sensitivity = specificity = 90% and prevalence as you computed inQ29. O a. 0.0625O b. 0.026367O c. 0.03967O d. 0.0397O e. 0.0497O f. 0.00587
Which of the following is/are true statement(s) about the power of a study? Select all that apply.Note: Wrong selection results in points deduction on this question. Please choose wisely O a.Given an effect size, increasing the sample size increases power O b. Given an effect size, increasing alpha cutoff increases power c. Power is invariant to the magnitude of effect size for a given alpha cutoff and sample size O d. Given an effect size, increasing the variability of samples increases power
For each scatterplot, choose the best type of correlation coefficient to use with this data. Choose... Neither Pearson not Spearman
What type of box model is suitable for computing the bootstrap confidence interval for paired datasets? O a.Re-centered two-box with replacement O b. One-box paired deltas with replacement c. Two-box resampling with replacement O d. One-box paired deltas without replacement O e. Big-box resampling with replacement
A study concluded that the Relative Risk of lung cancer for people who smoke compared to people who do not smoke is 1.7 with a 95% Cl of (1.2, 2.0). Which of the followingstatements is incorrect, based on this data alone? O a. People who smoke are 1.7 times more likely to get lung cancer than those who do not smoke. O b. Smoking causes lung cancer since RR is large and statistically significant O c. There is a significant association between lung cancer and smoking status O d. People who smoke are at a higher risk of lung cancer compared to those who do not smoke. O e. The probability of lung cancer is lower for those who do not smoke.
The histogram below shows the P-values for a prospective study based on 50 simulations. For alpha = 0.05 and 0.2, what are the power of the study? O a.96% and 74% respectively O b. 86% and 72% respectively О с.Power cannot be computed based on just this histogram O d. 14% and 28% respectively O e.4% and 26% respectively
Which of the following is/are true about the p-value? O a. The p-value can change if the individuals in the general population change (e.g., In a general population of coffee drinkers, 10/100 individuals arecoffee drinkers versus 300/1000 people are coffee drinkers) O b. The p-value is a conditional probability O c. The p-value is a frequentist probability Od. The p-value is low if the event is unlikely to happen if the null hypothesis is true. O e. The p-value can change if the general population size gets bigger or smaller (e.g., In a general population of coffee drinkers, 10/100 individuals are coffee drinkers versus 100/1000 people are coffee drinkers)
