All the tools & learning materials you need for study success - in one app.
Get started for freeFollowing are two probability histograms of binomial distributions. For each, specify whether the success probability is less than, equal to, or greater than 0.5.
In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.
Preeclampsia. Preeclampsia is a medical condition characterized by high blood pressure and protein in the urine of a pregnant woman. It is a serious condition that can be life-threatening to the mother and child. In the article "Women's Experiences Preeclampsia: Australian Action on Preeclampsia Survey of Wom and Their Confidants" (Journal of Pregnancy,Vol. 2011, Issue 1, Article ID 375653), C. East et al. examined the experiences of 68 women with preeclampsia. The following table provides a frequency distribution of instances of prenatal or infant death for infants of women with preeclampsia.
Suppose that one of these women with preeclampsia is randomly selected. Find the probability that the child of the woman selected
(a) died.
(b). died one week to six months after birth.
(c). lived at least six weeks.
In Exercises 5.16-5.26, express your probability answers as a decimal rounded to three places.
Housing Units. The U.S. Census Bureau publishes data on housing units in American Housing Survey for the United States. The following table provides a frequency distribution for the number of rooms in U.S. housing units. The frequencies are in thousands.
A housing unit is selected at random. Find the probability that the housing unit obtained has
(a) four rooms.
(b) more than four rooms.
(c) one or two rooms.
(d) fewer than one room.
(e) one or more rooms.
In each of Exercises 5.167-5.172, we have provided the number of trials and success probability for Bernoulli trials. LetX denote the total number of successes. Determine the required probabilities by using
(a) the binomial probability formula, Formula 5.4 on page 236. Round your probability answers to three decimal places.
(b) TableVII in AppendixA. Compare your answer here to that in part (a).
Constract a venn diagram representing the event.
Part (a) .
Part (b).
