Answer 1

Solution:- Let, mean Sales volume is 14. The manager wants to conduct a research Study to see whether the new bonus plan increases so the sales volume from the present 14 automobiles 1. per month In this case, the research hypothesis is that the new plans will provide a mean number of automobiles Sold exceeding 14; ie U714 → A research hypothesis should be stated as the alternative hypothesis, the appropriate null and alternative hypotheses for the Study are: Ho & usly Ha % M714 Hence, ? If the Sample results indicate that Ho can't be rejected researcher can't conclude that the new bonus plan is better

Perhaps more research should be conducted and subsequent testing If the Sample results indicate that Ho can be rejected, the researcher can make the inference that Ha : M714 is true With this conclusion, the researchers gain the Statistical Support necessary to state that the new bonus plan increases the mean Sales volume Per month Sales with the new plan should be considered.
