According to the "January theory," if the stock market is up for the month Qnt 351 week two mystatlab problems January, it will be up for the year. If it is down in January, it will be down for the year. According to an article in The Wall Street Journal, this theory held for 28 out of the last 34 years.

Suppose there is no truth to this theory; that is, the probability it is either up or down is 0. What is the probability this could occur by chance? Customers experiencing technical difficulty with their internet cable hookup may call an number for technical support.

It takes the technician between seconds and 14 minutes to resolve the problem. The distribution of this support time follows the uniform distribution. What are the values for a and b in minutes? What is the mean time to resolve the problem?

What is the standard deviation of the time? What percent of the problems take more than 5 minutes to resolve? What are the end points of these two times?

A normal population has a mean of 21 and a standard deviation of 6. Compute the z value associated with What proportion of the population is between 21 and 24?

What proportion of the population is less than 17? The manufacturer of a laser printer reports the mean number of pages a cartridge will print before it needs replacing is 12, The distribution of pages printed per cartridge closely follows the normal probability distribution and the standard deviation is pages.

The manufacturer wants to provide guidelines to potential customers as to how long they can expect a cartridge to last.

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.
