In order to meet the specifications of a client, a manufacturer of widgets needs to make their widgets 1200 mm long. A quality assurance expert randomly selects 159 widgets and calculates the mean length to be 1202 mm. If it is known that the population standard deviation is1.24 mm....
- construct the 95% confidence interval about the population mean.
- does it seem as though the client's specifications have been met?
- if we constructed a 99% confidence interval, would the range between the upper limit and lower limit be wider or narrower? Why do you think this is so?

In order to meet specifications, widgets must have a given time
coefficient of at least 18. A sample of 100 widgets is drawn from
the day’s production and tested and 21 of them had time
coefficients less than 18.
a. Find a 98% confidence interval for the proportion of widgets
manufactured that day which fail to meet specifications.
b. Repeat question a., but for 95% confidence interval.
c. For each of these two levels of confidence, find the sample
size...

A supervisor needs to produce widgets. Two machines are
able to make the widgets. Machine A takes 2 hours to set up and can
then make widgets at a rate of 80 per hour. The machine does not
have to be stopped once it is running. Machine B takes 30 minutes
to set up and can then widgets at the rate of 60 per hour, but
every 2 hours the machine has to be stopped and lubricated.
Lubrication takes 30...
