However, with inevitable fluctuations in the filling process, a quality-control manager randomly samples 12 jars and measures their contents. The task is to analyze whether the data is normally distributed, calculate the sample standard deviation, and construct a 99% confidence interval for the population standard deviation.---**Part (a): Verification of Normal Distribution**To verify if the data is normally distributed, a normal probability plot is used. The correct plot should show an approximate linear relationship between the expected z-scores and the observed data. Out of four options (A, B, C, D), choose the plot that demonstrates this linearity, confirming normality.**Options:**- **Plot A**: Displays a scattered relationship, indicating non-normal distribution.- **Plot B**: Shows a clear linear trend.- **Plot C**: Demonstrates some clustering, suggesting deviation from normality.- **Plot D**: Scattered with no clear linearity.**Question:** Are the data normally distributed?- [ ] No- [ ] Yes**Correct Answer:** Plot B shows the most linearity, suggesting the data are normally distributed.---**Part (b): Determination of Sample Standard Deviation**Calculate the sample standard deviation (s) using the observed data, rounding to three decimal places as needed.**Formula:**\[ s = \sqrt{\frac{\sum (x_i - \bar{x})^2}{n-1}} \]---**Part (c): Confidence Interval for Population Standard Deviation**Construct a 99% confidence interval for the population standard deviation based on the sample data. Select the correct range:- **Option A**: Suggests a 99% chance that the true population standard deviation is between two values (to be calculated and inserted in the blanks). - **Option B**: Refers to repeated samples, indicating 99% of them will have a sample standard deviation within a specified range (calculated and filled in the blanks).**Correct Approach:** Use statistical methods (such as a chi-square distribution) to find the interval and fill in the blanks.---**Conclusion:**This exercise demonstrates practical methods of assessing normality in data, calculating standard deviation, and constructing confidence intervals. Understanding these concepts is crucial for quality control and statistical analysis in manufacturing processes.
