1. Brokers generally agree that bonds are a better
investment during times of low interest rates than during times of
high interest rates. A survey of executives during a time of low
interest rates showed that 57% of them had some retirement funds
invested in bonds. Assume this percentage is constant for bond
market investment by executives with retirement funds. Suppose
interest rates have risen lately and the proportion of executives
with retirement investment money in the bond market may have
dropped. To test this idea, a researcher randomly
samples 200 executives who have retirement funds. Of
these, 95 now have retirement funds invested in bonds.
For α = .10, does the test show enough evidence
to declare that the proportion of executives with retirement fund
investments in the bond market is significantly lower than .57?
The value of the test statistic is __.
