5- As a result of a preliminary study, it was seen that 80 of the machines were working as a result of 100 observations made at random intervals. a) Specify sample size for 95% confidence level and 10% absolute error. For 95% confidence level: Z = 1.96 (taken from normal curve area table) b) What would the sample size be if the absolute error was accepted as 5% instead of 10%7 c) If the confidence level is 80.64% and the absolute error is 10%, what will the sample size be?
