a research hypothesis is that the variance of stopping distances of automobiles on wetpavement is substantially greater than the variance of stopping distances of automobileson dry pavement. in the research study, 16 automobiles traveling at the same speeds aretested for stopping distances on wet pavement and then tested for stopping distances ondry pavement. on wet pavement, the standard deviation of stopping distances is 32 feet.on dry pavement, the standard deviation is 16 feet.a. at a .05 level of significance, do the sample data justify the conclusion that the variance in stopping distances on wet pavement is greater than the variance in stoppingdistances on dry pavement? what is the p-value?

Question

a research hypothesis is that the variance of stopping distances of automobiles on wet
pavement is substantially greater than the variance of stopping distances of automobiles
on dry pavement. in the research study, 16 automobiles traveling at the same speeds are
tested for stopping distances on wet pavement and then tested for stopping distances on
dry pavement. on wet pavement, the standard deviation of stopping distances is 32 feet.
on dry pavement, the standard deviation is 16 feet.
a. at a .05 level of significance, do the sample data justify the conclusion that the variance in stopping distances on wet pavement is greater than the variance in stopping
distances on dry pavement? what is the p-value?
