Having trouble with question 1c) 1)You need to construct a confidence interval to see which employees are not happy with a policy.  You took a simple random sample of 17 employees out of 134.  Construct the confidence interval for the population proportion.  Use the formula for this one. Use a significance level of 98%. 1a) The critical value is (3 decimals like 2.187)= 2.326 1b) The margin of error is (use 3 decimals for every number on the formula) (3 decimals: .084) =.067   1c) The confidence interval is (  ,  )  (first one has two decimals .01, the second one three decimals .273)   1d) The opinion was that the real number for all employees is 30%. What can you conclude from the result that you got from part C? = It is definitely not 30%

2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.
