Compound Probability
Compound probability can be defined as the probability of the two events which are independent. It can be defined as the multiplication of the probability of two events that are not dependent.
Tree diagram
Probability theory is a branch of mathematics that deals with the subject of probability. Although there are many different concepts of probability, probability theory expresses the definition mathematically through a series of axioms. Usually, these axioms express probability in terms of a probability space, which assigns a measure with values ranging from 0 to 1 to a set of outcomes known as the sample space. An event is a subset of these outcomes that is described.
Conditional Probability
By definition, the term probability is expressed as a part of mathematics where the chance of an event that may either occur or not is evaluated and expressed in numerical terms. The range of the value within which probability can be expressed is between 0 and 1. The higher the chance of an event occurring, the closer is its value to be 1. If the probability of an event is 1, it means that the event will happen under all considered circumstances. Similarly, if the probability is exactly 0, then no matter the situation, the event will never occur.
Question
Transcribed Image Text:Data on the numbers of hospital admissions resulting from motor vehicle crashes are given below for Fridays on the 6th of a month and Fridays on the following 13th of the
same month. Assume that the paired sample data is a simple random sample and that the differences have a distribution that is approximately normal. Construct a 95%
confidence interval estimate of the mean of the population of differences between hospital admissions. Use the confidence interval to test the claim that when the 13th day
of a month falls on a Friday, the numbers of hospital admissions from motor vehicle crashes are not affected.

In this example, µ, is the mean value of the differences d for the population of all pairs of data, where each individual difference d is defined as the number of hospital
admissions on Friday the 6th minus the number of hospital admissions on Friday the 13th. Find the 95% confidence interval.
(Round to two decimal places as needed.)

Based on the confidence interval, can one reject the claim that when the 13th day of a month falls on a Friday, the numbers of hospital admissions from motor vehicle
crashes are not affected?
O A. Yes, because the confidence interval does not include zero.
O B. Yes, because the confidence interval includes zero.
O C. No, because the confidence interval includes zero.
O D. No, because the confidence interval does not include zero.
