Suppose that the proportion of investors who are risk-averse (that is, try to avoid risk in their investment decisions) is though to be at least 0.6. A financial advisor believes that the proportion is actually less than 0.6. A survey of 30 investors found that 18 of them were risk-averse. Formulate a one-sample hypothesis test for a proportion to test this belief. Determine the null hypothesis, Ho, and the alternative hypothesis, H,. Ho * 2 0.6 H; I < 0.6 (Type integers or decimals. Do not round.) Compute the test statistic. (Round to two decimal places as needed.)
