Hi excellent Tutor,

Can you please help me solve these questions?

Thanks.

Question 3 (Hypothesis Test) In this question, you will construct a randomisation distribution using the data in the following table. These data are based on a study in which patients with HIV were randomly assigned to two groups, with one group getting cannabis and the other getting a placebo. All the patients had severe pain and the response variable was whether or not pain was reduced by at least 30%. In answering the questions below make sure you use appropriate notation where necessary. Pain Reduced Pain Not Reduced . Is cannabis more effective than a placebo in relieving pain in HIV patients? Determine at a 5% significance level (a). (i) What are the null and alternative hypotheses for the research question highlighted above? (ii) what are the sample proportions of patients with reduced pain in each group and what is the sample statistic? (iii) What assumption do we make in creating the randomisation distribution? (iv) Use StatKey to generate a randomisation distribution of 10,000 differences in sample proportions. Please include your randomisation distribution in your assignment solutions. (v) Describe the shape and centre of your randomisation distribution in one or two sentences. (vi) Use your randomisation distribution to calculate a p-value for the test. (vii) Use your p-value to assess the strength of evidence against the null hypothesis, in context
