The sample space of possible outcomes is given by:
Explanation of Solution
Calculation:
The given information is that there are three people in a family and each person
Sample Space:
A sample space is the set of all possible outcomes of a random experiment.
Here, there are three persons in a family and each person is assigned to three stations.
The 27 possible outcomes are as follows:
It is given that the event B is all three people go to different stations.
Therefore, the sample space for the event B is given by:
Complement of an event A is the set of all outcomes that are not in A. It is denoted as
The event
Therefore, the sample space for the event
b.
Obtain the sample space for the event
b.

Answer to Problem 13E
The sample space of possible outcomes is given by:
Explanation of Solution
Calculation:
It is given that the event A is that all three people go to the same station.
Then the possibilities for event A are either three persons are assigned to station 1 or three persons are assigned to station 2 or three persons are assigned to station 3.
Therefore the sample space for A is given by:
It is given that the event B is that all three people go to the different stations.
Therefore, the sample space for the event B is given by:
The sample space for the event
Therefore, the sample space for the event

A sociologist hypothesizes that the crime rate is higher in areas with higher poverty rate and lower median income. She col- lects data on the crime rate (crimes per 100,000 residents), the poverty rate (in %), and the median income (in $1,000s) from 41 New England cities.

- Can you help me solve problem 38 with steps im stuck.arrow_forwardHow do the samples hold up to the efficiency test? What percentages of the samples pass or fail the test? What would be the likelihood of having the following specific number of efficiency test failures in the next 300 processors tested? 1 failures, 5 failures, 10 failures and 20 failures.arrow_forwardThe battery temperatures are a major concern for us. Can you analyze and describe the sample data? What are the average and median temperatures? How much variability is there in the temperatures? Is there anything that stands out? Our engineers’ assumption is that the temperature data is normally distributed. If that is the case, what would be the likelihood that the Safety Zone temperature will exceed 5.15 degrees? What is the probability that the Safety Zone temperature will be less than 4.65 degrees? What is the actual percentage of samples that exceed 5.25 degrees or are less than 4.75 degrees? Is the manufacturing process producing units with stable Safety Zone temperatures? Can you check if there are any apparent changes in the temperature pattern? Are there any outliers? A closer look at the Z-scores should help you in this regard.arrow_forward
