Let x represent the dollar amount spent on supermarket impulse buying in a 10-minute (unplanned) shopping interval. Based on a newspaper article, the mean of the x distribution is about 42$ and the estimated standard deviation is about 6$.

From the central theorem, what can you say about the probability distribution of the average amount set by these customers due to impulse buying?

What is the probability that is between $40 and $447 (Round your answer to four decimal places) (d) in part (b), we used the average amount spent, computed for 40 customers. In part(s), we used X, the amount spent by only one customer. The answers to parts (b) and (c) are very different Why would this happen? The standard deviation is smaller for the distribution than it is for the x distribution The standard deviation is larger for the distribution than it is for the distribution The mean is larger for the distribution than it is for the distribution The samples is smaller for the distribution than it is for the distribution The stribution is approximately normal while the x distribution is not normal In this comple, is a much more predictable or reliable statistic thanx Consider that almost all marketing strategies and sales pitches are designed for the average customer and not the individual customer. How does the central limit theo tell us that the average customer is much more predictable than the individual customer? The centralimit theorum tells us that the standard deviation of the sample mean is much smaller than the population standard deviation. Thus, the average customers more predictable than the individual customer The central them tells us that smal samples have small standard deviations on average. Thus, the average customer is more predictable than the individual mer about 542 and the estimated standard deviation about 6 meget dolor amount pesta permanet imple buying in a 10 minute (unglarized shopping interval Based on a newer wide, the mean of the distribution USE SALT (*) Consider a random sample of customen, ench of whom has 10 minutes of unplanned shopping time in supermarket.
