Chapter 4, Problem 4.1LB

Three coins are tossed.

  1. Give an example of a simple event.
  2. Give an example of a joint event.
  3. What is the complement of a head on the first toss?
  4. What does the sample space consist of?

a)

Expert Solution
Check Mark
To determine

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)

Expert Solution
Check Mark
To determine

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)

Expert Solution
Check Mark
To determine

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)

Expert Solution
Check Mark
To determine

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:

The table below shows the estimated effects for a logistic regression model with squamous cell esophageal cancer (Y = 1, yes; Y = 0, no) as the response. Smoking status (S) equals 1 for at least one pack per day and 0 otherwise, alcohol consumption (A) equals the average number of alcohoic drinks consumed per day, and race (R) equals 1 for blacks and 0 for whites. Variable Effect (β) P-value Intercept -7.00 <0.01 Alcohol use 0.10 0.03 Smoking 1.20 <0.01 Race 0.30 0.02 Race × smoking 0.20 0.04 Write-out the prediction equation (i.e., the logistic regression model) when R = 0 and again when R = 1. Find the fitted Y S conditional odds ratio in each case.  Next, write-out the logistic regression model when S = 0 and again when S = 1. Find the fitted Y R conditional odds ratio in each case.
The chi-squared goodness-of-fit test can be used to test if data comes from a specific continuous distribution by binning the data to make it categorical. Using the OpenIntro Statistics county_complete dataset, test the hypothesis that the persons_per_household 2019 values come from a normal distribution with mean and standard deviation equal to that variable's mean and standard deviation. Use signficance level a = 0.01. In your solution you should 1. Formulate the hypotheses 2. Fill in this table Range (-⁰⁰, 2.34] (2.34, 2.81] (2.81, 3.27] (3.27,00) Observed 802 Expected 854.2 The first row has been filled in. That should give you a hint for how to calculate the expected frequencies. Remember that the expected frequencies are calculated under the assumption that the null hypothesis is true. FYI, the bounderies for each range were obtained using JASP's drag-and-drop cut function with 8 levels. Then some of the groups were merged. 3. Check any conditions required by the chi-squared…
Suppose that you want to estimate the mean monthly gross income of all households in your local community. You decide to estimate this population parameter by calling 150 randomly selected residents and asking each individual to report the household’s monthly income. Assume that you use the local phone directory as the frame in selecting the households to be included in your sample.  What are some possible sources of error that might arise in your effort to estimate the population mean?
