Let x represent the dollar amount spend on supermarket impulse buying in a 10-minute unplanned shopping interval. The mean of this distribution is µ=$25 and the standard deviation is =$10. If we assume the x distribution is approximately normal: (a) What is the probability that a randomly selected shopper will spend between $18 and $22? (b) Consider a random sample of n = 100 shoppers. What is the probability that is between $18 and $22? (c) State two different ways we know the distribution from part (b) is normally distributed.

The mean checkout time in the express lane of a large grocery store is 2.7 minutes, and the standard deviation is 0.6 minutes. The distribution of checkout times is non-normal (for one thing, it can be a lot longer than 2.7 minutes, but it can only be so short).(a) What is the probability that a randomly-selected customer will take less than 3 minutes? 0.69150.3085 It cannot be determined from the information given. (b) What is the probability that the average time of two randomly-selected customers will take less than 3 minutes? It cannot be determined from the information given.0.2389 0.7611 (c) The probability that the average time of 64 randomly-selected customers will take less than 2.8 minutes is (d) The probability that the average time of 81 randomly-selected customers will take less than 2.8 minutes is (e) The probability that the average time of 225 randomly-selected customers will take less than 2.8 minutes is (f) The probability that the average time of 400…
Let x represent the dollar amount spend on supermarket impulse buying in a 10-minute unplanned shopping interval. The mean of this distribution is µ=$25 and the standard deviation is =$10. If we assume the x distribution is approximately normal: (1) What is the probability that a randomly selected shopper will spend between $18 and $22? (1) Consider a random sample of n = 100 shoppers. What is the probability that is between $18 and $22? (2) State two different ways we know the distribution from part (b) is normally distributed.
After visiting the Titanic, Captain Brain and Mr. Pinky are taking the Alvin submarine back to the surface of the water. They start 1900 meters below the surface of the water, and ascend at 62 meters per hour.Note: under the water is a negative number.Write an equation to model this situation (use mm for meters and hh for hours)
Suppose that all the students registered to the probability and statistics course have to buy textbook. The 28 % of all students demand a new book, on the other hand the other 72 % want a used text book. Consider randomly selecting 40 purchasers.a. What are the mean value and standard deviation of the number who want a new copy of thebook?b. What is the probability that the number who want brand-new books is more than 1.5σ awayfrom the mean value?c. The bookstore has 30 new and 30 used textbooks in stock. If 40 people come in one by one topurchase this text, what is the probability that all 40 will get the type of book they want fromcurrent stock? [Hint: Let X = the number who want a new copy. For what values of X will all 40get what they want?]
': Consider a puzzle is created where the amount of time it takes an individual to solve the puzzle follows a normal distribution with a standard deviation of 2 minutes. a) If a sample of 13 individuals was collected, what is the probability the sample mean time required to solve the puzzle would be within 1.2 minutes of the population mean? b) What would the required sample size be if we wanted the sample mean to be within half a minute of the population mean with a probability of .9?
Suppose samples of size 100 are drawn randomly from a normal population that has a mean of 20 and a standard deviation of 5. What is the probability of observing a sample mean less than 19? 0.4772 0.3413 0.9772 0.0228 0.0580
Answer a and b
A sample of size 86 will be drawn from a population with mean 90 and standard deviation 24. Use the TI-83 Plus/TI-84 Plus calculator. Part: 0 / 2 Part 1 of 2 (a) Find the probability that x will be between 89 and 91. Round the answer to at least four decimal places. The probability that x will be between 89 and 91 is X
