A manufacturer claims that a particular kind of solar shade can reduce the ambient temperature by 2 degrees centigrade over traditional materials. Over random times over several days, temperatures were taken at the same time under a traditional awning and an adjacent awning using this brand of solar shade. In the attachment, column A is the traditional and column B is the new shade. Prove whether or not the manufacturer’s claims are true to 95% confidence level.
First, we figure out the difference for each.
Then we figure out the mean and standard deviation for the …
This solution provides a proof to determine whether the manufacturer’s claims are true at a 95% confidence level.
