company supplies a tool for pouring cold medicine into bottles in such a way that the standard deviation of the contents is 4.15 g. A new filling process is tested on 86 bottles and the standard deviation for this sample is 3.84 g. Use a 0.10 significance level to test the claim that the new process dispenses amounts with a standard deviation less than the standard deviation of 4.15 g for the old process. Is the new process better in the sense of dispensing amounts that are more consistent? Assume that a simple random sample is selected from a normally distributed population. What are the correct hypotheses for this test? Hoσ = H₁: 4.15 g 4.15 g Calculate the value of the test statistic. (Round to two decimal places as needed.)

A machine company supplies a tool for pouring cold medicine into bottles in such a way that the standard deviation of the contents is 4.15 g. A new filling process is tested on 86 bottles and the
standard deviation for this sample is 3.84 g. Use a 0.10 significance level to test the claim that the new process dispenses amounts with a standard deviation less than the standard deviation of 4.15
g for the old process. Is the new process better in the sense of dispensing amounts that are more consistent? Assume that a simple random sample is selected from a normally distributed
population.
What are the correct hypotheses for this test?
Ho:
4.15 g
H₁:
4.15 g
Calculate the value of the test statistic.
(Round to two decimal places as needed.)
