Test statistic for difference between two population means

Reference no: EM1318718

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.

	No stenosis (n = 356)		Stenosis
	Mean	sd	Mean	sd
bG	5.3	1.4	5.1	0.8

a. 0.0001

b. 0.0256

c. 0.0623

d. 0.1576

e. 0.3523
