Find the critical value + za/2 that corresponds to the given confidence level. 10A) A confidence level of 95% 10B) A confidence level of 90% left tail area right tail area left tail area right tail area S = = = 0 0 Za/2 = Za/2 = 10C) A confidence level of 99% 10D) A confidence level of 92% left tail area right tail area left tail area right tail area = 0 0 Za/2 = Za/2 = _10E) A confidence level of 96% 10F) A confidence level of 97% left tail area right tail area left tail area right tail area 0 Za/2 = Za/2 = 10G) A confidence level of 94% 10H) A confidence level of 91% left tail area right tail area left tail area right tail area = 0 Za/2 = Za/2 = 11. Use the information given to find p and & (round to 2 decimal places). Then find the Margin of Error (E) in estimating the population proportion by using a sample proportion. Show the set up and answer. Round the answer to 2 decimal places. 11A) n = 100, x = 20 , a - .05 11B) n =192 , x = 67 , a = .04 P =. q = Ip . q E = Za/2 Set up for E = E = E =Construct a Confidence Interval for the population proportion p given n , x and the the confidence level. Show the set-up and the answer for j and E . State the confidence Interval Cl for p . Round to 2 decimal places. 12) n = 80, x = 20, Confidence Level = 95% Find px Find E: Confidence Interval for p: p- E
