Data Science Interview Challenge

## Data Science Interview Challenge

# Challenge 4: Confidence Intervals

In the realm of statistics, confidence intervals provide a range within which a population parameter is likely to fall. They offer a degree of certainty around a sample statistic. For example, if you survey a group of people about their height, and compute an average height of 170 cm with a 95% confidence interval of (168 cm, 172 cm), this suggests that you're 95% confident that this range would cover the real height of the entire population.

Task

In this exercise, leveraging a random sample data set, you'll:

- Compute the sample mean and the standard error.
- Determine the 95% confidence interval for the mean of the sample data.
