60&tags=autosave#question3762878_3 Paused A random sample of 36 values is drawn from a mound-shaped and symmetric distribution. The sample mean is 8 and the sample standard deviation is 2. Use a level of significance of 0.05 to conduct a two-tailed test of the claim that the population mean is 7.5. LO USE SALT (a) Is it appropriate to use a Student's t distribution? Explain. Yes, because the x distribution is mound-shaped and symmetric and o is unknown. O No, the x distribution is skewed left. O No, the x distribution is skewed right. O No, the x distribution is not symmetric. No, o is known. How many degrees of freedom do we use? (b) What are the hypotheses? OH : H = 7. 5 ; H : H 7.5 O Ho: H > 7.5 ; H: H = 7.5 (c) Compute the t value of the sample test statistic. (Round your answer to three decimal places.) t = (d) Estimate the P-value for the test. O P-value > 0.250 0. 100
