### Constructing a Confidence Interval for Newborn Girls' WeightsHere are summary statistics for randomly selected weights of newborn girls: - Sample size (\(n\)): 158- Sample mean (\(\bar{x}\)): 27.9 hg- Sample standard deviation (\(s\)): 6.6 hgWe aim to construct a confidence interval estimate of the mean weight using a 98% confidence level. **Analysis Question**:Are these results very different from the previous confidence interval \( 27.1 \text{ hg} < \mu < 29.7 \text{ hg} \) based on a smaller sample size of 20, with a sample mean (\(\bar{x}\)) of 28.4 hg, and sample standard deviation (\(s\)) of 2.3 hg?#### Confidence Interval Calculation:To find the confidence interval for the population mean \(\mu\):\[ \text{Note: Values are to be rounded to one decimal place as needed.} \]\[ \_\_\_\_ \text{ hg} < \mu < \_\_\_\_ \text{ hg} \] This exercise will help determine how the larger sample size affects the precision of our confidence interval estimates compared to a smaller sample size.

Imagine that you obtain a random sample of 125 M&M candies, and you notice that 28% of these candies are blue. If we convert the sample percentage of 0.28 to a sample proportion (by dividing 28 by 100), we get 0.28.
A learn-to-type software program claims that it can improve your typing skills. To test the claim and possibly help yourself out, you and six of your friends decide to try the program and see what happens. Use the table below to construct an 80% confidence interval for the true mean change in the typing speeds for people who have completed the typing program. Let Population 1 be the typing speed before taking the program and Population 2 be the typing speed after taking the program. Round the endpoints of the interval to one decimal place, if necessary.
