Answer #1

From the given information,

The required answers are,

10a. As null hypothesis contains "=" sign hence required answer is,

a) H0: µ1 = µ2

10b. As alternative hypothesis contains <,>,≠ sign hence required answer is,

d) H1: X1 ≠ X2

11. As on the title this is one sample test and test statistic is "t"

Hence, the required answer is,

a) one-sample t-test
