A rare form of malignant tumor occurs in 11 children in a million, so its probability is 0.000011. Four cases of this tumor occurred in a certain town, which had 17 comma 513 children. a. Assuming that this tumor occurs as usual, find the mean number of cases in groups of 17 comma 513 children. b. Using the unrounded mean from part (a ), find the probability that the number of tumor cases in a group of 17 comma 513...

1.9 The probability W(n) that an event characterized by a probability p occurs n times in N trials was shown to be given by the binomial distribution Consider a situation where the probability p is small (p « 1) and where one is interested in the case n < N. (Note that if N is large, W(n) becomes very small if n → N because of the smallness of the factor P" when p 《I. Hence W(n) is indeed only...
9. The principle of redundancy is used when system reliability is improved through redundant or backup components. Assume that a student's alarm clock has a 10.1% daily failure rate. Complete parts (a) through (d) below. c. What is the probability of not being awakened if the student uses three independent alarm clocks? (Round to five decimal places as needed.) 14.In a market research survey of 2006 motorists, 281 said that they made an obscene gesture in the previous month. Complete...
According to CDC estimates, more than two million people in the United States are sickened each year with antibiotic-resistant infections, with at least 23,000 dying as a result. Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next CDC, gonorrhea has an estimated 800,000 cases occurring annually, with approximately 30% of those cases resistant to any antibiotic. Assume a physician treats 7 cases of gonorrhea during a...
Question 12 of 13 > According to CDC estimates, more than two million people in the United States are sickened each year with antibiotic-resistant infections, with at least 23,000 dying as a result. Antibiotic resistance occurs when disease-causing microbes become resistant to antibiotic drug therapy. Because this resistance is typically genetic and transferred to the next generations of microbes, it is a very serious public health problem. Of the three infections considered most serious by the CDC, gonorrhea has an...
