Question
The effectiveness of a blood-pressure drug is being investigated. An experimenter finds that, on average, the reduction in systolic blood pressure is 30 for a sample of size 14 and standard deviation 8. Estimate how much the drug will lower a typical patient’s systolic blood pressure using a 99% confidence level. Round your answers to three decimal places, and use four decimal places for any interim calculations.

We are 99% confident that the interval (\_\_\_\_, \_\_\_\_) contains the true population mean \( \mu \) amount the drug will lower a typical patient’s systolic blood pressure.

Which conditions are required for the validity of the interval? Select all that apply.

- [ ] Random sample
- [ ] Normal population
- [ ] \( \sigma \) known
- [ ] \( \mu \) known
