The Nero Match Company sells matchboxes that are supposed to have an average of 40 matches per box, with o8. A random sample of 94 matchboxes shows the average number of matches per bax to be 42.7. Using a 1% level of significance, can you say that the average number o matches per box is more than 40? What are we testing in this problem? O single mean O single proportion (a) what is the level of significance? State the null and alternate hypotheses. O H H 40; HH< 40 O Hạ: p= 40; H,p> 40 O Hạ: p = 40; H P < 40 O Hgi H= 40; Hu> 40 O Hai p- 40, H:p- 40 O H H 40; H 40 (b) what sampling distribution will you use? what assumptions are you making?
