Question

Question 11 15 pts A production manager believes that a container filling line for peanut cans is under-filling the 1 lb containers. He collects a sample of 50 peanut cans and weighs them. He computes a test value of Z -1.84. At the .05 level of significance, can the manager conclude that the production line is under- filling the containers? What about the .01 level of significance?

My dear student I am allow to solve one question at one time so I solved first one (As per HomeworkLib policy)

Giren :- H=50 Z test = -1.84 Level of significan (2) = 0.05 The null and alternative hypothesis are: Hoit=1 Haillel (Left failed test) Ztests -1.84 P-value = P(Z < Ztest) = P(Z <=184) (using Z table) so, [P-raue & d (Level of significance ) since. P-value less than significance level so Twe Reject the Ho Conclusion: The Cans are under filling Now, we take - Level of significan(a)= 0.01 FP-value sal Since P-value is greater than level of significance (a) we fail to Reject Hol Conclusion - At levee orol, Manager wile accept Ho and conclude that the can is not under filling.
