Question
Transcribed Image Text:In a study, workers were tested to determine the effects of exposure to a certain enzyme
during production of detergent. In people with no lung dysfunction, a typical air flow
rate is 0.80. We can use a confidence interval to determine whether exposure to the
enzyme seems to have an effect on the air flow rate.
In this study, the air flow rates for 19 workers were measured. Rather than listing the 19
measurements, I will tell you that the sum of these 19 measurements is 14.57. (You need
to calculate 7 from this information.) Assume that the rates are normally distributed
with o = 0.09.
Construct a 95% confidence interval for the population mean air flow rate for workers
exposed to the enzyme.
Expert Solution
Step 1
As the population standard devoation is known, we will use z distribution.
The value of z at the 95%confidence level is 1.96, which can be found by using the standard normal table.
