Question Answered step-by-step 1.1 What are the null and alternative hypotheses for this research… Image transcription textA researcher was tasked with determining if treated wood siding was more resistant to fire. Two kinds of siding were tested in a lab. They were exposed to flame and then the researcher recorded how many minutes it took for the siding to combust. The results of the tests are included below: Test # Standard Wood Siding Treated Wood Siding 1 3 5 2 3 7 3 2 4 4 5 5 5 7 8 6 2 6 7 3 4 Mean Standard Deviation N… Show more1.1 What are the null and alternative hypotheses for this research question? (assume a non-directional hypothesis)1.2 Calculate the t-statistic for this data set.1.3 Assuming a p-value of 0.05, do you reject the null hypothesis? (HINT: you will need to refer to Appendix B; remember that you are using a non-directional hypothesis) 1.4 Based on your answer to 1.3, how do you answer the original research question? Is the treated wood siding more resistant? 1.5 It is always important to check the assumptions of a test you are using. What are some assumptions made about the above data set in order for a t-test to be valid? (give 2 examples)  Math Statistics and Probability STATS 120 Share QuestionEmailCopy link Comments (0)
