A chemist for a paint company conducted an experiment to investigate whether a new outdoor paint will last longer than the older paint. Fifty blocks made from the same wood were randomly assigned to be painted with either the new paint or the old paint. The blocks were placed into a weather-controlled room that simulated extreme weather conditions such as ice, temperature, wind, and sleet. After one month in the room, the blocks were removed, and each block was rated on texture, shine, brightness of color, and chipping. The results showed that the blocks painted with the new paint generally had higher ratings than the blocks painted with the old paint. However, an analysis of the results found that the difference in ratings was not statistically significant. What can be concluded from the experiment

Multiple-choice questions have a special grading rule determined by your instructor. assume that your instructor has decided to grade these questions in the following way: if you submit an incorrect answer to a multiple-choice question with n options, you will lose 1/(nâ’1) of the credit for that question. just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.if a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question? multiple-choice questions have a special grading rule determined by your instructor. assume that your instructor has decided to grade these questions in the following way: if you submit an incorrect answer to a multiple-choice question with options, you will lose of the credit for that question. just like the similar multiple-choice penalty on most standardized tests, this rule is necessary to prevent random guessing.if a multiple-choice question has five answer choices and you submit one wrong answer before getting the question correct, how much credit will you lose for that part of the question? 100% 50% 33% 25% 20%
