A CBS News/New York Times poll of 1,000 adults in the United States asked the question, "Do you think global warming will have an impact on you during yourlifetime?" (CBS News website). Consider the responses by age groups shown below.AgeResponse18-2930+Yes134293No131432Unsure28a. What is the probability that a respondent 18-29 years of age thinks that global warming will not have an impact during his/her lifetime (to 4 decimals)?b. What is the probability that a respondent 30+ years of age thinks that global warming will not have an impact during his/her lifetime (to 4 decimals)?c. For a randomly selected respondent, what is the probability that a respondent answers yes (to 3 decimals)?d. Based on the survey results, does there appear to be a difference between ages 18-29 and 30+ regarding concern over global warming?

In the July 29, 2001, issue of The Journal News (Hamilton, Ohio), Lynn Elber of the Associated Press reported that “while 40 percent of American families own a television set with a V-chip installed to block designated programs with sex and violence, only 17 percent of those parents use the device.”(a)Use the report’s results to find an estimate of the probability that a randomly selected American family has used a V-chip to block programs containing sex and violence.find P(V and U)According to the report, more than 50 percent of parents have used the TV rating system (TV-14, etc.) to control their children’s TV viewing. How does this compare to the percentage using the V-chip?
This problem involves empirical probability. The table shows the breakdown of 95 thousand single parents on active duty in the U.S. military in a certain year. All numbers are in thousands and rounded to the nearest thousand. Use the data in the table to find the probability that a randomly selected single parent in the U.S. military is in the Army.

24 John works in an appliance store. His sales commission depends on the number of units sold per period, and the overall average price of all units sold. The following is a report of his sales effort in a given month. The report shows the price and the percent of total units sold at that price. Percent of total units Item Price sold A $1,640 10% B 1270 25% C 860 35% D 460 20% E 200 10% The overall mean price of all items sold is, a $930.64 b $912.39 c $894.50 d $876.96
Brain tumors in children are rare: the base rate is only about 1/10,000. A child with a tumor is very likely to have occasional headaches: 99 out of 100 do. But there are many other reasons a child can have a headache: of those who do not have a tumor, 1 in 10 have occasional headaches. 1. Given that a child has occasional headaches (H), what it the probability that he or she has a brain tumor (T)? Show your work. 2. Name a behavioral bias that may occur when estimating the probability that your child has a brain tumor. Would this bias lead to under-or-overestimate that probability? Explain. 3. Among children with headaches (H), 999/1000 will ultimately be fine (F). Suppose that a physician using a simple test can correctly determine whether the child is fine or not in 95/100 of children with headaches. Given that the doctor after performing the test gives the patient a green light (G), what is the probability that the child really will be fine? Show your work.. Page 1 of 1 175 words…
