1). Dr. Johnson hypothesizes that people who practice yoga for one hour a day will have higher scores on a life satisfaction test than those in the general population. On a standard life satisfaction test, the overall population mean, or u, is 88.3 and the standard deviation, or , is 6.4. The researcher gives this same test to a random sample of 24 individuals who regularly practice yoga for at least one hour a day. Their sample mean is 90.5, with a sample 3 of 5.5. H . I]. H . A- What is your 3m] value? Is this a one-tailed or two-tailed test? What is the obtained 2 value? Numerator = 0. = 0' Y @ Standard error of the mean (denominator) = Z : Apply your decision rule: Compare your obtained 2 with your critical 2. Does it fall in the region of rejection or not? Do you reject or fail to reject the null hypothesis? Explain your results? Do people who practice yoga have higher life satisfaction scores than people in the general population
