The annual production of a manufacturing company that produces generators follows a normal distribution with a mean µ=1200 and standard deviation σ=100.
1) The shading area for the probability between 1100 and 1300 units is?
2) The probability of producing between 1100 and 1350 units is ?
3) The probability of producing less than 1200 units is?
4) The probability of producing between 1200 and 1350 units is .

5) A student intends to measure the boiling temperature of a certain liquid. His experimental sample size is 6. The experimental results revealed a sample mean of 100.81. It is known from previous record that the standard deviation of the population is 1.2 degrees.
-A 95% confidence interval for the population mean is ?
-Would it be reasonable to conclude that the population mean is 101?
