Here are summary statistics for the weights of Pepsi in randomly selected cans: n=36, x=0.82412 lb, s=0.00567 lb. Use a confidence level of 99% to complete parts (a) through (d) below. a. Identify the critical value ta/2 used for finding the margin of error. ¹/2 = 0 (Round to two decimal places as needed.) b. Find the margin of error. E= lb (Round to five decimal places as needed.). c. Find the confidence interval estimate of u. XII lb<μ

Certainly! Here is the transcription of the text visible in the image: --- **E = | |** *(Round to five decimal places as needed.)* **c. Find the confidence interval estimate of μ.** **|b < μ < |** *(Round to five decimal places as needed.)* **d. Write a brief statement that interprets the confidence interval. Choose the correct answer below.** - **A.** One has 99% confidence that the interval from the lower bound to the upper bound contains the true value of the population mean weight of Pepsi in a can. - **B.** One has 99% confidence that the sample mean weight of Pepsi in a can is equal to the population mean weight of Pepsi in a can. - **C.** There is a 99% chance that the true value of the population mean weight of Pepsi in a can will fall between the lower bound and the upper bound. - **D.** Approximately 99% of sample mean weights of Pepsi in a can will fall between the lower bound and the upper bound. --- No graphs or diagrams appear to be in the image.

### Statistical Analysis of Pepsi Can Weights #### Summary Statistics For a study on the weights of Pepsi in randomly selected cans, the summary statistics are as follows: - Sample size (\( n \)): 36 - Sample mean (\( \bar{x} \)): 0.82412 lb - Sample standard deviation (\( s \)): 0.00567 lb We are using a confidence level of 99% to complete the following tasks: #### Tasks a. **Identify the Critical Value (\( t_{\alpha/2} \))** - This value is needed to find the margin of error. - Round to two decimal places as necessary. b. **Find the Margin of Error (\( E \))** - Round to five decimal places as necessary. c. **Find the Confidence Interval Estimate of \(\mu\)** - Represented as \( \bar{x} - E < \mu < \bar{x} + E \) - Round to five decimal places as necessary. d. **Interpret the Confidence Interval** - Choose the correct statement from the options provided. > **Navigation Options:** > Use the icons at the bottom of the page for different functions, such as returning to the previous section or continuing to the next part of the analysis. Select `Next` to proceed with evaluating this statistical analysis. % The above illustrates the statistical procedure for evaluating the weight of randomly selected Pepsi cans, focusing on obtaining a confidence interval using sample data.
