Identify the assumptions that would be needed for this problem i) Population is normally distributed ii) Since n>30 the sample mean is normally distributed iii)) np and nq are greater than or equal to 5. iv) Sigma is unknown Use a significance level of a = 0.05 to test the claim that u = 32.6. The sample data consist of 15 scores for which x = 6 and s=0. Use the traditional method of testing hypotheses. O ii only O i only O i and iv only O iii only
