Over a span of 10 years (120 months), you collect the following data on the monthly returns large and small cap stock indices:

	Large return (%)	Small return (%)	Difference (large - small)
Mean	1.37	1.1	1.37 - 1.1
SD	4.32	5.16	3.03

Calculate the test statistic for paired-observation test equality of the means of these two indices.

Bonus thinking question: can you reject the hypothesis that they are equal?
