Suppose a researcher examines a possible relationship in the population and the results are found to not be statistically significant.

If yes, explain why; if no, describe how the researcher should state their conclusion regarding a possible relationship.
Question 2
Suppose a company says they deliver their packages in 2 days or less, on average, and you are concerned that the packages are taking longer to deliver than promised. You conduct a hypothesis test to help you answer this question. Which alternative hypothesis would give you the best chance of detecting an actual problem, a one-sided alternative (average time of delivering packages is greater than 2 days) or a two-sided alternative (average time delivering packages is not equal to 2 days)? Explain your answer. If both have the same chance, explain why.
