Homework Answers
b)
since there are total 8 cavity and 1,2 or 3 is 3 out of them
probability =3/8 =0.375
c)
P(neither from 3 nor 4 )=P(from other 6) =6/8 =0.75

2.2.14 Your answer is incorrect. Try again Plastic parts produced by an injection-molding operation are checked for conformance to specifications. Each tool contains 13 cavities in which parts are produced, and these parts fall into a conveyor when the press opens. An inspector chooses 2 part(s) from among the 13 at random. Three cavities are affected by a temperature malfunction that results in parts that do not conform to specifications Round your answers to four decimal places a) What is...

A batch of 536 containers for frozen orange juice contains 6 that are defective. Two are selected, at random, without replacement from the batch. a) What is the probability that the second one selected is defective given that the first one was defective? Round your answer to five decimal places (e.g. 98.76543). b) What is the probability that both are defective? Round your answer to seven decimal places (e.g. 98.7654321). c) What is the probability that both are acceptable? Round...

A particularly long traffic light on your morning commute is green 40% of the time that you approach it. Assume that each morning represents an independent trial. Let denote the number of mornings the light is green. a) Over 10 mornings, what is the probability that the light is green on exactly 4 days? Round your answer to three decimal places (e.g. 98.765) b) Over 20 mornings, what is the probability that the light is green on exactly 8 days?...

A manufacturer is interested in the output voltage of a power supply used in a PC. Output voltage is assumed to be normally distributed with standard deviation 0.3 volt, and the manufacturer wishes to test H, u = 5 volts against H: # 5 volts, using n=8 units. Use z-values rounded to two decimal places. Calculate the P-value if the observed statistic is (a) = 5.1...
