**Statistical Analysis of Reaction Times in Older Women**

**Study Summary:**
A group of twenty-five women aged between 70 and 80 were randomly selected to participate in a special program aimed at decreasing reaction time. Upon completion of the course, these women exhibited an average reaction time of 688 milliseconds. For comparison, the mean reaction time for the general population of women in this age bracket is known to be 750 milliseconds, with a standard deviation of 300 milliseconds.

**Tasks for Analysis:**

(a) **Compute a 95% Confidence Interval:**
- Calculate the 95% confidence interval for $ \mu $, the population mean reaction time, for women who have taken part in the program.

(b) **Conduct a Hypothesis Test:**
- Determine whether the educational course had a statistically significant effect on the reaction times by performing a hypothesis test.

This exercise will enable students to apply statistical concepts such as confidence intervals and hypothesis testing to real-world scenarios, enhancing their understanding of statistical analysis methods.

This is because nausea is common for people who have the flu. From past studies you know that about 33% of people who get the flu experience nausea. You collected data on 2371 patients who were taking Tamiflu to relieve symtoms of the flu, and found that 841 experienced nausea. Use a 0.01 significance level to test the claim that the percentage of people who take Tamiflu for the relief of flu symtoms and experience nausea is greater than 33%. *.** ▸ Ezra Mill X HH Chief Be X V H₁: ?
