Chapter 4.5, Problem 44E
According to the Open Doors 2011 Report, 9.5% of all full-time U.S. undergraduate students studied abroad during the 2009–2010 academic year (Institute of International Education, November 14, 2011). Assume that participation records show women make up 60% of the students who studied abroad during the 2009–2010 academic year, but women make up only 49% of the students who didn’t participate.
- a. Let A1 = the student studied abroad during the 2009–2010 academic year
A2 = the student did not study abroad during the 2009–2010 academic year
W = the student is a female student
Using the given information, what are the values for P(A1), P(A2), P(W | A1), and P(W | A2)?
- b. What is the
probability that a female student studied abroad during the 2009–2010 academic year? - c. What is the probability that a male student studied abroad during the 2009–2010 academic year?
- d. Given the preceding results, what were the percentage of women and the percentage of men studying full-time during the 2009–2010 academic year?

- You’re scrolling through Instagram and you notice that a lot of people are posting selfies. This piques yourcuriosity and you want to estimate the percentage of photos on Instagram that are selfies.(a) (5 points) Is there a “ground truth” for the percentage of selfies on Instagram? Why or why not?(b) (5 points) Is it possible to estimate the ground truth percentage of selfies on Instagram?Irrespective of your answer to the previous question, you decide to pull up n = 250 randomly chosenphotos from your friends’ Instagram accounts and find that 32% of these photos are selfies.(c) (15 points) Determine which of the following is an observation, a variable, a sample statistic (valuecalculated based on the observed sample), or a population parameter.• A photo on Instagram.• Whether or not a photo is a selfie.• Percentage of all photos on Instagram that are selfies.• 32%.(d) (5 points) Based on the sample you collected, do you think 32% is a reliable ballpark estimate for theground truth…arrow_forwardCan you explain this statement below in layman's terms? Secondary Analysis with Generalized Linear Mixed Model with clustering for Hospital Center and ICUvs Ward EnrolmentIn a secondary adjusted analysis we used generalized linear mixed models with random effects forcenter (a stratification variable in the primary analyses). In this analysis, the relative risk for the primaryoutcome of 90-day mortality for 7 versus 14 days of antibiotics was 0.90 (95% Confidence Interval [CI]0.78, 1.05).arrow_forwardIn a crossover trial comparing a new drug to a standard, π denotes the probabilitythat the new one is judged better. It is desired to estimate π and test H0 : π = 0.5against H1 : π = 0.5. In 20 independent observations, the new drug is better eachtime.(a) Find and plot the likelihood function.
