A lake contains 4 distinct types of fish. Suppose that each fish caught is equally likely to be any one of these types. Let Y denote the number of fish that need be caught to obtain at least one of each type.
a. Give an interval
b. Using the one-sided Chebyshev inequality, how many fish need we plan on catching so as to be at least 90 percent certain of obtaining at least one of each type?

- Which of the following pairs of sets are equivalent or equal?arrow_forwardState whether the data described below are discrete or continuous, and explain why. The number of car accidents on a given stretch of highway each year Choose the correct answer below. O A. The data are continuous because the data can take on any value in an interval. O B. The data are discrete because the data can take on any value in an interval. O C. The data are discrete because the data can only take on specific values. OD. The data are continuous because the data can only take on specific values.arrow_forwardA study of 900 working women showed that their feelings changed throughout the day. The line graph shows 15 different times in a day and the average level of happiness for the women at each time. Based on the information given by the graph, represent the set using the Average Level of Happiness at Different Times of Day roster method. {x | x is a time of the day when 1< average level of happiness < 2} noon 10 p.m. 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 Time of Day .... .

Subtracting the length of time required by the FDA for testing and approval of the drug provides the actual patent life for the drug-that is, the length of time that the company has to recover research and development costs and to make a profit. The distribution of the lengths of actual patent lives for new drugs is given below: | 8 | 0.20 | 6 | 0.14 a) What is the value of “?" so that the above is the probability distribution? |9 0.08 | 11 0.22 Year, y 4 5 10 12 føy) 0.05 |0.07 0.17 0.01 b) Find the mean and standard deviation of patent life for a new drug. c) What is the probability of a patent living at least ten years for new drugs?arrow_forward

- 2arrow_forwardTeachers get courses assigned to teach each semester. For each instructor, there are the courses that the instructor can teach based on the skill set of the instructor, and there are courses that the teacher would rather teach all the time, closer to their specialization. To be able to teach in any department, a teacher must be able to teach more than the favorite courses. Let X denote the proportion of teachers who teach the whole spectrum of courses taught in a department, and Y the proportion of teachers who teach the courses they specialize in. Let X and Y have the joint density function : f(x,y)=2(x+y),0<y<x<1 (a) Given that 10% of the teachers teach the whole spectrum of courses, what is the probability that fewer than 5% teach their favorite courses? (b) What is the expected percentage of teachers teaching their favorite courses when the proportion of teaching the whole spectrum is 0.7?arrow_forward4arrow_forward
