Unformatted text preview: the proportion was 36% however with 93% confidence interval we can say that in a longer running test it would be between 23.7% and 49.75% 3. For this experiment since I determined the samples to be independent from each other since they are two different types of plastic pipe. The first thing we have to determine is whether of not the means of the two samples are significantly different. We should declare that if they are more than 10% different then they are significantly different. After running our test we determined that the Pvalue is .253, since it is bigger than 10%. Also with 97% Confidence Interval we can determine that the difference of the average deflection is between (4.09, 12.62). I noticed that the difference interval is higher on the positive side, this means that it is skewed 3 times to the side of the first sample. Therefore the first sample contains a higher mean than the second one....
