The alternative and null hypotheses is given below,

Null Hypothesis, H0: μ1 - μ2 = 0

Alternative Hypothesis, Ha: μ1 - μ2 < 0

Compound Variance is given as,

sp = sqrt( s12n1+s22n2)

sp = sqrt(16973 + 112.3673)

sp = 1.9632

Test statistic of z is,

z = (x1bar - x2bar)/sp

z = (69 - 71)/1.9632

z = -1.02

P-value Approach, P=0.1539 as long as P>= 0.

As P-value >= 0.01, failing to rule out the null hypothesis.
