Answer.....

Based on the confidence interval, does it appear that the neck size differs from 0.5 mm? 1) Consider a claim that the average head size is different from 0.5 mm. Now do a hypothesis test to see if your informal conclusion was correct. State the hypothesis in symbols, and define the parameter. Note that you can write mu for u. A B State the value of the test statistic and p-value from the printout. Note that you do not have to actually calculate the test statistic, or adjust the p-value in any way. It is correct for the hypothesis being tested. p-value = Briefly assess the strength of the evidence. Which of the following best explains the strength of the P-value? Select one: Oi very strong evidence for Ha Oil. strong evidence for Ha OIL good evidence for Ha W. moderate evidence for Ha no evidence for HaWhich of the following is the correct conclusion in the context of the problem? Select one: a. If the assumptions hold and this production run is representative of all production runs, we have moderate evidence to conclude that the average head size is different from 0.5 mm, for the population of all Little People LEGO toys. O b. If the assumptions hold and this production run is representative of all production runs, we have moderate evidence that the average head size is different from 0.5 mm, for the population of all Little People LEGO toys. c. If the assumptions hold and this production run is representative of all production runs, we can conclude that the average head size is different from 0.5 mm, for the population of all Little People LEGO toys. Old. If the assumptions hold and this production run is representative of all production runs, we have moderate evidence that the average head size is different from 0.5 mm, for this sample of Little People LEGO toys
