Of 1,050 randomly selected adults, 360 identified themselves as manual laborers, 280 identified themselves as non-manual wage earners, 250 identified themselves as mid-level managers, and 160 identified themselves as executives. In the survey, 82% of manual laborers preferred trucks, 62% of non-manual wage earners preferred trucks, 54% of mid-level managers preferred trucks, and 26% of executives preferred trucks. Suppose we want to lower the sampling error. What is one way to accomplish that? O decrease the sample size O decrease the standard deviation increase the standard deviation O increase the sample size O lower the proportion
