A study was performed concerning risk factors for carotid artery stenosis (narrowing) among 464 men born in 1914and residing in the city of Malmo, Sweden. The table below shows a comparison of blood - glucose (bG) levels between men with and without carotid artery stenosis (narrowing).
Perform the appropriate test for a difference in mean blood glucose and report the p-value for the two - tailed test of significance, assuming that the variances are equal.
