A well-known brokerage firm executive claimed that 50% of investors are currently confident of meeting their investment goals. An XYZ Investor Optimism Survey, conducted over a two week period, found that in a sample of 600 people, 57% of them said they are confident of meeting their goals. Test the claim that the proportion of people who are confident is larger than 50% at the 0.10 significance level. The null and alternative hypothesis would be: Ho:P Но: р — 0.5 Но: и < 0.5 Но:д H1:p + 0.5 H1: µ > 0.5 H1:µ + 0.5 0.5 Но: д > 0.5 Но:р < 0.5 Но:р > 0.5 Hi:и < 0.5 Hі:р > 0.5 Hi:р < 0.5 The test is: left-tailed two-tailed right-tailed The test statistic is: (to 3 decimals) The p-value is: (to 4 decimals) Based on this we: Fail to reject the null hypothesis Reject the null hypothesis
