Consider the R output below.

n mean sd F 31 126.5 8.4 M 44 138.3 19.8

Welch Two Sample t-test

data: systolic by gender t = -3.528, df = 62, p-value = 0.0008

alternative hypothesis: true difference in means is not equal to 0 95 percent confidence interval: ? ? sample estimates: mean in group F mean in group M 126.5 138.3

consider the following statements.

(i) The analysis uses the procedure that assumes that the population variances are unequal. (ii) The population means are not equal. (iii) Both populations must be normal in order for the analysis to be valid.

Determine which of the above statements are True (1) or False (2).
