What is an example of a distribution channel?
Distribution channels include wholesalers, retailers, distributors, and the Internet. In a direct distribution channel, the manufacturer sells directly to the consumer. Indirect channels involve multiple intermediaries before the product ends up in the hands of the consumer.
Are there any questions about the normal distribution?
In this article, various questions regarding the normal distribution are answered. The effects of the mean and the standard deviation on the shape of the normal distribution are analysed. We will describe how to obtain probabilities of intervals and on the other hand how to construct confidence intervals for a certain level of confidence.
When does the normal distribution reach its peak?
The following is the plot of the normal distribution with mean and standard deviation . The normal distribution with these exact two values ( and ) is known specifically by the name: standard normal distribution. The standard normal distribution reaches its peak when and is symmetric about the -axis.
How to calculate the normal distribution of satellite dishes?
(i) Determine P(X< 150) (3 marks) (ii) Determine, to one decimal place, the time exceeded by 10 per cent of installations. (4 marks) The time, Y minutes, taken by Sid Slow to install a satellite dish may also be assumed to be a normal random variable, but with 170) = 0.14 and = 0.03.
