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 children is 0 or 1. c. What is the probability of more than one case? d. Does the cluster of four cases appear to be attributable to random chance? Why or why not? a. The mean number of cases is nothing. (Type an integer or decimal rounded to three decimal places as needed.) b. The probability that the number of cases is exactly 0 or 1 is nothing. (Round to three decimal places as needed.) c. The probability of more than one case is nothing. (Round to three decimal places as needed.) d. Let a probability of 0.05 or less be "very small," and let a probability of 0.95 or more be "very large". Does the cluster of four cases appear to be attributable to random chance? Why or why not?

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...
