The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 34.5 for a sample of size 907 and standard deviation 13.2. Estimate how much the drug will lower a typical patient's systolic blood pressure (using a 95% confidence level). Enter your answer as a tri-linear inequality accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).

Question
**The Effectiveness of a Blood-Pressure Drug**

An experiment is being conducted to investigate the effectiveness of a blood-pressure drug. The findings indicate that, on average, the reduction in systolic blood pressure is 34.5 mmHg for a sample size of 907 individuals, with a standard deviation of 13.2 mmHg.

**Objective:**
Estimate how much the drug will reduce a typical patient's systolic blood pressure with a 95% confidence level.

**Instructions:**
Enter your answer as a tri-linear inequality, accurate to one decimal place (since the sample statistics are reported to one decimal place). 

**Input Format:**
\[ \_\_ < \mu < \_\_ \]

- Your answer should be calculated without any preliminary rounding.
