Confidence Intervals and Hypothesis Testing
TOPIC NAME
Determining null and alternative hypotheses
Transcribed Image Text:Records from a toy manufacturing company showed that the mean time
that the top-selling toy captured children's attention was 40 minutes. A
competing company strongly suspects that the mean time will be less
than 40 minutes for the new generation of children, and wishes to carry
out a hypothesis test. State the null hypothesis and the alternative
hypothesis ", that they would use for this test.

Answer this question and discuss what that means in relation to a two-sided hypothesis test. Specifically, do these results allow us to infer anything about the claim stated in the problem? Are the results practically significant? Should the company that created Medicine A stand behind their claim of being non-drowsy based on these results?

Did the new process from 2 months before yield data showing a reduction in cost? Or was it merely a matter of chance… Too soon to do the data dance? So they set about the business of crafting a hypothesis test In order to conclude which process was best. With the null hypothesis meaning “status quo”, no change evident They quickly concluded H0 could not stand, as was their true intent. Just one month later, they realized their grave mistake! A Type II error would have been so much safer, for goodness sake. Alas, their final huddle was a sad one with HR Director Bob. He told them to go back to training school as each was now in need of a new job. What was the likely managerial mood and outcome on the days immediately following the (erroneous) conclusion to reject this null hypothesis?
