Concept explainers
Three coins are tossed.
- Give an example of a simple
event . - Give an example of a joint event.
- What is the complement of a head on the first toss?
- What does the
sample space consist of?
a)
To provide an example of a simple event.
Answer to Problem 4.1LB
Getting a head on first coin.
Explanation of Solution
Given:
3 Coins tossed
A simple event refers to the event that occur one at a time and have only one outcome at a time.
The example of the simple event is “Getting a head on first coin.”
b)
To provide an example of a joint event.
Answer to Problem 4.1LB
Getting a head on first and third coin.
Explanation of Solution
A joint event means when two events occur at a time.
The example of the simple event is “Getting a head on first and third coin.”
c)
To provide an example of a compliment event.
Answer to Problem 4.1LB
Tail on the first toss.
Explanation of Solution
Complementary events are refers to the event when there are two outcomes like having a job or not having a job.
The complimentary event of head on first toss is that “tail on the first toss.”
d)
To explain the sample space.
Answer to Problem 4.1LB
{HHH,HHT,HTH,HTT,THH,THT,TTH,TTT}
Explanation of Solution
A sample space is a set of all the possible outcomes of an experiment.
The sample space for the given three coins experiment is given below:
{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

- 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. Give the ML estimate of π (Hint: youmay use the plot function in R)arrow_forward
