A well-known brokerage firm executive claimed that 60% 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 200 people, 58% of them said they are confident of meeting their goals. Test the claim that the proportion of people who are confident is smaller than 60% at the 0.005 significance level. The null and alternative hypothesis would be: Ho:µ = 0.6 Ho: p < 0.6 Ho:µ > 0.6 Họ:µ < 0.6 Ho:p = 0.6 Ho:p> 0.6 H1 : µ # 0.6 H1:p > 0.6 H1:µ < 0.6 H1:µ > 0.6 H1:p# 0.6 H1:p< 0.6 The test is: left-tailed right-tailed two-tailed The test statistic is: |(to 3 decimals) The p-value is: |(to 4 decimals)
