A statistical analysis of long distance phone calls made from the headquarters of Bricks and Clicks indicates the length of the calls have a mean of 300 seconds with a standard deviation of 40 seconds. If the length of the calls follows a normal distribution, What is the probability that the length of a random phone call is less than 200 seconds? That the length of a random phone call is between 220 and 370 seconds? That the length of the...
Q: A study of long-distance phone calls made from General Electric revealed the length of the calls, in minutes, follows the normal probability distribution. The mean length of time per call was 5.5 minutes and the standard deviation was 1.3 minutes. Find the interquartile range of this distribution
A reception desk receives phone calls at a rate of 4 calls per 10 minutes. What is the probability of receiving no calls in 5 minute period?
Approximately 16% of the calls to an airline reservation phone line result in a reservation being made. (a) Suppose that an operator handles 10 calls. What is the probability that none of the 10 calls result in a reservation? (Give the answer to 3 decimal places.) (b) What assumption did you make to calculate the probability in Part (a)? Calls are independent. Calls are dependent. (c) What is the probability that at least one call results in a reservation being...
Approximately 19% of the calls to an airline reservation phone line result in a reservation being made. (a) Suppose that an operator handles 10 calls. What is the probability that none of the 10 calls result in a reservation? (Give the answer to 3 decimal places.) (b) What assumption did you make to calculate the probability in Part (a)? Calls are independent. Calls are dependent. (C) What is the probability that at least one call results in a reservation being...
An agency is having problems with personal phone calls made during working hours. Each minute of a personal call costs the agency $0.10 in wasted wages. The agency decides to hire operators to monitor calls in order to attain the optimal number of personal calls (minimize total cost of personal calls). Number of Operators Total minutes of personal calls (per hour) 0 795 1 678 2 566 3 457 4 356 5 264 6 176 a. What is the most...
8. Data were collected on the lengths of all phone calls made by college students on cell phones during one month. Two measures of center (mean and median) for this distribution were identified as 2.5 minutes and 13.7 minutes. Which of the following is true? The mean is 2.5 minutes and the median is 13.7 minutes because the distribution of the lengths is phone calls is most likely left-skewed. The mean is 2.5 minutes and the median is 13.7 minutes...
