Question 53 (20 points) The J.O. Supplies Company buys calculators from a Korean supplier. The probability of a defective calculator is 10%. If 14 calculators are selected at random, what is the probability that less than 5 of the calculators will be defective? (Ch.6) I U Format
A company buys tires from three suppliers A, B and C. Supplier A has a record of delivering tires containing 8% defective, whereas supplier B has a defective rate of only 4% and supplier C has defective rate of 12%. Suppose 35% of current supply comes from supplier A, 30% from supplier C and rest from supplier B. If a tire is selected at random, find the probability: (a) that the tire is NOT defective; (b) given the selected tire...
Suppose that 10% of a certain batch of calculators have a defective case, and that 18% have defective batteries. Also, 6% have both a defective case and defective batteries. A calculator is selected from the batch at random. Find the probability that the calculator has a good case and good batteries. The probability that the calculator has a good case and good batteries is (Type an integer or a decimal.)
B) Suppose that 11% of a certain batch of calculators have a defective case, and that 13% have defective batteries. Also, 5% have both a defective case and defective batteries. A calculator is selected from the batch at random. Find the probability that the calculator has a good case and good batteries.
apter 1. Consider the following data on distances traveled by 100 people to visit the local park. 1-8 30 25 20 15 10 9-16 17-24 25-32 33-40 Expand and construct the table adding columns for relative frequency and cumulative relative frequency. Then plot Histogram, Frequency Polygon and Ogive Curve. 2. Math test anxiety can be found throughout the general population. A study of 200 seniors at a local high school was conducted. The following table was produced from the data....
A quality control engineer inspects a random sample of 30 calculators from an incoming batch of size 150 and accepts the lot if at most 4 are not in working condition; otherwise the entire lot must be inspected with the cost charged to the vendor. Suppose the lot contains 5 defective calculators. a.) What is the probability that such a lot will be accepted without further inspection? b.) Given the third calculator tested is the first calculator to be defective,...
2. Suppose an electronics store receives 30 graphing calculators. a. How many different ways can the store select 4 calculators from among the 30 to send to a customer? b. If 6 of the calculators are defective, how many of the selections contain no defective calculators? c. Use the results of parts a and b to calculate the probability that the customer receives at least one defective calculator. d. How many of these selections contain 1 defective calculators? Combine this...
A sample of 4 different calculators is randomly selected from a group containing 18 that are defective and 35 that have no defects. What is the probability that at least one of the calculators is defective?
A sample of 5 different calculators is randomly selected from a group containing 10 that are defective and 8 that have no defects. Assume that the sample is taken with replacement. What is the probability that at least one of the calculators is defective? Express your answer as a percentage rounded to the nearest hundredth.
