Question 4 The probability that your call to a service line is answered in less than 30 seconds is 0.75. Assume that your calls are independent. (a) if you call 10 times, what is the probability that exactly nine of your callis are answered within 30 seconds? (b) If you call 20 times, what is the probability that at least 13 calls are answered in more than 30 seconds? (C) if you call 20 times, what is the mean number of calls that are answered in less than 30 seconds? Use the editor to format your answer Question 5

Use the editor to format your answer Question 5 In an accelerator center, an experiment needs a 1.41-cm thick aluminum cylinder (http://puhep1.princeton.edu/mumu/ target/Solenoid_Coil.pdf ). Suppose that the thickness of a cylinder has a normal distribution with a mean of 1.41 cm and a standard deviation of 0.1 mm. (a) What is the probability that a thickness is greater than 1.42 cm? (b) What thickness is exceeded by 95% of the samples? (C) if the specifications require that the thickness is between 1.41 cm and 1.44 cm, what proportion of the samples meet specifications?
