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 call is between 180 and 280 seconds?
- The length of the call is greater than 330 seconds?
- What would be the length of time a call would reach in order for it to be considered in the upper 5% of the longest calls?

A study of long-distance phone calls made from General Electric Corporate Headquarters in Fairfield, Connecticut, revealed the length of the calls, in minutes, follows the normal probability distribution. The mean length of time per call was 3.8 minutes and the standard deviation was 0.70 minutes. Use Appendix B.3. What is the probability that calls last between 3.8 and 4.5 minutes?

Suppose that the length of long distance phone calls, measured in minutes, is known to have an exponential distribution with the average length of a call equal to $14 minutes. The lambda of this distribution is .0714 Correct The probability that the length of a phone call is longer than 18 is P(x ≥ 18) = .2766 Correct The probability that the length of a phone call is shorter than 11 is P(x ≤ 11) = .5440 Correct The probability...

Imagine that you are a consultant who is building a statistical model to predict how long a customer will remain with a firm (i.e., customer retention). Research demonstrates that both consumer satisfaction and calculated brand commitment should help predict customer retention. Consumer satisfaction is defined as a customer’s overall evaluation of the performance of a product or service to date.78 Calculated brand commitment is a consumer’s dependence on a brand’s benefits due to a lack of choices or switching costs.79...

How does this article relate to the factors of productions in economics? From Music to Maps, How Apple’s iPhone Changed Business Ten years ago, hailing a cab meant waiving one's arm at passing traffic, consumers routinely purchased cameras, and a phone was something people made calls on. The iPhone, released a decade ago this month, changed all of that and more, sparking a business transformation as sweeping as the one triggered by the personal computer in the 1980s. Apple Inc.'s...

1. Many companies use a incoming shipments of parts, raw materials, and so on. In the electronics industry, component parts are commonly shipped from suppliers in large lots. Inspection of a sample of n components can be viewed as the n trials of a binomial experimem. The outcome for each component tested (trialD will be that the component is classified as good or defective defective components in the lot do not exceed 1 %. Suppose a random sample of fiver...
