The following data from Schechter et al. [1973] deal with sodium chloride preference as related to hypertension. Two groups, 12 normal and 10 hypertensive subjects, were isolated for a week and compared with respect to Na+ intake. The following are the average daily Na+ intakes (in milligrams):

Normal 10.22 .20 .02 .60 .0 43 .1 45 .8 63 .61 .80 .0 3.7 0.0
Hypertensive 92.8 54 .8 51 .6 61 .7 250.8 84 .5 34 .7 62 .2 11 .0 39

It is known that the distribution of Na+ intake is heavily skewed to the left. Compare the average daily Na+ intake of the hypertensive subjects with that of the normal volunteers at 5% significance level
