Question
A batch of 3000 inverters from the production line has a mean output voltage of 337.8 V and the Standard deviation of the output voltage is 3.105. If the voltages of the produced inverters are assumed to be
- The number of inverters with output voltages greater than 336.9 V.
- The number of inverters with output voltages less than 337.1 V,
- The number of inverters with output voltages between 336.2 V and 339.8 V.
For this problem you should use the table of z-values shown in Figure below.

- At a hair salon, customers arrive at the rate of 3 customers per hour. The standard deviation of the time between two consecutive arrivals is estimated as 9 minutes.
