Discuss the below:
Q1. The company believes that it averages about the same weight per bag in each of two production lines. To test this idea, they will perform a hypothesis test to compare the two lines at the alpha level of 0.05. State the null and alternative hypotheses:
Q2. If the test calculates a sample Z of 1.69, what is the corresponding p value?
Q3. If we have two samples, one with a mean of 20.5 and standard deviation of 0.91 and one with a mean of 22.4 and standard deviation of 0.32, what might we be able to tell about these two samples and how would we test it? What else might we need to know?
