28 Dec Suppose that an independent research
Suppose that an independent research company was tasked with testing the validity of complaints against a pesticide manufacturing firm for under-filling their 20 lb bags of pesticide. Past experience has shown that the amount of pesticide dispensed by the machines that fill the bags follows a normal distribution with a mean of 20 lb and a standard deviation of 0.6 lb.
To verify the validity of the complaints, a researcher randomly selected 16 of the firm’s 20 lb pesticide bags and recorded the following weights.
19.42,19.69,20.25,19.89,18.54,19.76,19.24,18.8,19.82,18.61,20.1,19.07,20.04,19.27,19.52,19.52
The mean weight of the 16 bags collected was 19.471 lb. Calculate the value of the one-sample z ? statistic.
