Sounderpandian pg - 295- 352 for further reference Non - parametric test: these are used mainly when population distributrions are not normal Testing hypothesis about population means Ho: μ = or > or < specified value i. σ (x bar - μ29 / σ/√ n ii. σ (x bar - μ29 / σ/√ n Ho: μ = or > or < specified value population is normal but σ is not known (x bar - μ29 / s /√ n Testing hypothesis about population proportions Ho: p= or > or < specified value i. If binomial probabilities can be calculated i.e. n, the no. of trials & p probability of success should be given; sample size should be ≤ 500 P (X = x) = n c x .p x .q n-x
