Test the claim that the population proportion of successes does not equal 0.50. Use a level of Significance of 0.05. (a) Can a normal distribution be used for the distribution? Explain. 0 Yes, n-p and n-q are both less than 5. O No, n-p is greater than 5, but n-q is less than 5. 0 Yes, n-p and no are both greater than 5. O No, n-p and n~q are both less than 5. O No, no is greater than S, but n~p is less than 5. (b) State the hypotheses. O HO: p = 0.5; H1: p > 0.5 O HO: p
