Hi can you please answer these multiple choice questions all relating to the information in the first image, no working out necessary. Thanks :)

Questions 45 - 48 concern the following idea: A study was done on rental properties in Perth to investigate if the mean weekly rent had changed from last year when the mean weekly rent was $415. A random sample of 201 rental properties gave a sample mean of $425 and a sample standard deviation of $50. Let u be the current population mean weekly rent in Perth. We are seeking to answer the question: "Is there evidence that the mean Perth rental price has change from last year?" Select the correct hypotheses to answer this question: A a. H041 = 425 H1: \"#425 m b. Ho: [.1 = 415 H1: W415 '77": Ho: =415 H1: =415 'T'd-Ho: =425 H1: )_(=425 What is the value of tobs when testing the hypotheses in Q45? O a. 2.84 b. 1.96 O c. 0.20 Od. 20.05If the p-value for this test was found to be 0.006, which of the following would be the correct decision? O a. At the 2.5% level of significance, there is not significant evidence to reject H1. Ob. At the 2.5% level of significance, there is significant evidence to reject H1 and accept Ho. OC. At the 2.5% level of significance, there is not significant evidence to reject Ho. Od. At the 2.5% level of significance, there is significant evidence to reject Ho and accept H1.If we were using the critical value method to test the hypotheses in Q45, with (I = 0.05, which of the following would be the correct critical value to use?
