A particular manufacturing plant has three machines which produce resistors. Each machine sometimes pmduces resistors which are defective. The data collected consists of whether or not the resistor is defective and the machine that produced it. A random sample of 931'] resistors produced from each of the three machines is obtained so that, in total: 27% resistors are sampled. The results are summarized in the following contingency table. Machine E E C Total W No BED 901 35? 2513 m [Ilefective'iI Use these data for exercises 13-11 13. [2 points} Mat kind of data is this? Brie?y explain. 14. [2 points} 'What sampling strategy was used to collect the data'iI 15. [2 points} Calculate the probability that a resistor was produced by machine 13. lfi. [2 points} Calculate the the probability that a resistor is defective given that it was produced by machine E. 1?. (2 points} Are the ev-ts that machine 13 produced the resistor and the resistor is de- fective independent? Brie?y explain using probabilities. The probability that a given tourist goes to the amusement park is [1.46 and the probability that the tourist goes to the water park is [1.59. Additionally, the probability that the tourist goes to the amusement park and the water park is [1.22. Find the probabilities described in exercises 13—2G. 13. [2 points} A tourist goes to the amusement park or the water park. 19. [2 points} A tourist goes to the water park but not to the amusement park. 2H. [2 points} A tourist does not visit the amusement park and does not go to the water park.
