An old scale displays a weight that is uniformly distributed between the real weight ±10 lbs. For example for a person with weight 100 lbs, the scale will show a weight uniformly distributed between 90 and 110. Consider the null hypothesis that a person weighs 100 lbs, and the alternative hypothesis that the weight is lower. What is the p -value (in percentage) of 91? unanswered What is the p -value (in percentage) of 90? unanswered What is the highest weight in lbs for which we can reject the null hypothesis with significance level 10% ?
