The Federal Reserve Board of Governors recently changed the reporting of its stance on monetary policy from what they termed a "policy bias" to a "balance of risks". A researcher wished to see whether there had been a change in the way financial analysts were interpreting the change in reporting. When the "policy bias" reporting method was used, it was known that only 35% of the Board's decisions were correctly anticipated by analysts in their reports. For the "balance of risks" method, the researcher took a random sample of 50 analysts' reports and found that 24 of these correctly anticipated the Board's decision. Assume that the test is to be carried out at the 5% level.

1. State the direction of the alternative hypothesis used to test whether the proportion of analysts correctly anticipating the Board's decision had changed. Type gt (greater than), ge (greater than or equal to), lt (less than), le (less than or equal to) or ne (not equal to) as appropriate in the box.
2. Calculate the test statistic, reporting your answer to two decimal places.

3. Use the tables to determine the p-value for the test, giving your answer to four decimal places.

4. Is the null hypothesis rejected for this test? Type yes or no.

5. Disregarding your answer for 4, if the null hypothesis was rejected at the 5% level, would the predictive accuracy of the claims in analysts' reports appear to have changed under the new system?
