Question 1183457
Ho: L-D  <=0
Ha: L-D >0
alpha =0.03 p{reject Ho|Ho true}
test is a t 0.985, df=64 (n1+n2-2)
critical value t >1.91
calculation is t=(355.20-265.60)/sqrt(151.50^2/31+(162.20^2/35))
=89.6/sqrt (1492.08)
=2.32
reject Ho and conclude that Limpopo is doing better than Durban.
p-value = 0.024 (calculator)
