HighTech Inc. randomly tests its employees about company policies. Last year in the 400 random tests conducted, 14 employees failed the test. You can use the following Excel model: A Sample Proportion n (sample size) 1 2 3 Alpha 4 Critical value 5 MOE 6 Lower Limit 7 Upper Limit Point estimate of the population proportion =14/400 400 .01 Margin of error |=ABS(NORM.S.INV(B3/2)) |=B4*SQRT(B1*(1-B1)/B2) =B1 - B5 =B1 + B5 a. What is the point estimate of the population proportion? (Round your answers to 1 decimal places.) B % b. What is the margin of error for a 99% confidence interval estimate? (Round your answers to 3 decimal places.) c. Compute the 99% confidence interval for the population proportion. (Round your answers to 3 decimal places.) Confidence interval is between d. Is it reasonable to conclude that 5% of the employees cannot pass the company policy test? Yes and No
