Here are summary statistics for the weights of Pepsi in randomly selected cans: \( \mathrm{n}=36, \overline{\mathrm{x}}=0.82407 \mathrm{lb}, \mathrm{s}=0.00569 \mathrm{lb} \). Use a confidence level of \( 99 \% \) to complete parts (a) through (d) below. b. Find the margin of error. E \( =.00258 \) lb (Round to five decimal places as needed.) c. Find the confidence interval estimate of \( \mu \). .82149 Ib < \( \mu \) < .82665 lb (Round to five decimal places as needed.) d. Write a brief statement that interprets the confidence interval. Choose the correct answer below. B. 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. 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. 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.

Divide the polynomials. The form of your answer should either be \( p(x) \) or \( p(x)+\frac{k}{x+7} \) where \( p(x) \) is a polynomial and \( k \) is an integer. \( \frac{x^{3}+5 x^{2}-9 x+30}{x+7}= \)
