Answer to Problem 95CE
The probability
Explanation of Solution
Calculation:
The given table shows that frequencies of the actual and predicted interest rate movements.
The given
Actual Change | |||
Forecast Change | Decline (A–) | Rise (A+) | Row Total |
Decline (F–) | 7 | 12 | 19 |
Rise (F+) | 9 | 6 | 15 |
Column Total | 16 | 18 | 34 |
The formula for finding the probability
Substitute 19 for ‘Frequency for the class F–’ and 34 for ‘Total frequencies in the distribution’
Therefore, the probability
