It does not matter whether we take a one-sided or two-sided alternative. Part d) Compute the test statistic (Please round your answer to three decimal places):
Part e) Assume all necessary conditions are met (random sampling, independence, large enough sample size). Which of the following approximate the sampling distribution of the test statistic in Part d: Normal distribution or t-distribution?
Part 1 Suppose that, based on data collected, you reject the null hypothesis. Which of the following could you conclude?
- There is sufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is less than the mean time for healthy adult Canadians.
- There is sufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is the same as the mean time for healthy adult Canadians.
- There is sufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is greater than the mean time for healthy adult Canadians.
- There is insufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is the same as the mean time for healthy adult Canadians.
- There is insufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is less than the mean time for healthy adult Canadians.
- There is insufficient evidence to suggest the mean time taken to solve the logic problem by UBC students is greater than the mean time for healthy adult Canadians.
Part g) Suppose that, based on data collected, you decide that UBC students perform better on average than healthy adult Canadians.
- It is possible that you are making a Type I error.
- It is possible that you are making a Type II error.
- It is certainly correct that UBC students perform better on average than healthy adult Canadians.
- It is certainly incorrect that UBC students perform better on average than healthy adult Canadians.
- There must have been a problem with the way the sample was obtained.
Part h) Suppose that, based on the data collected, you obtain a P-value of 0.02 (confirm this using the t-table): This
