In a random sample of 85 automobile engine crankshaft bearings, 10 have a surface finish that is rougher than the specifications allow. Therefore, a point estimate of the proportion of bearings in the population that exceeds the roughness specification is p = x/n = 10/85 = 0.12. Compute for a 95% two-sided confidence interval of p? %3D

Required information Jobe Concrete Products placed a new sand sifter into production 3 years ago. It had an installed cost of $100,000, a life of 5 years, and an anticipated salvage of $20,000. Book depreciation charges for the 3 years are $42,000, $18,000, and $22,000, respectively. If the sifter's market value today is $20,000, determine the difference between its current book value and its market value. The difference between its current book value and its market value is determined to be $
