The waiting times (in minutes) of a random sample of 22 people at a bank have a sample standard deviation of 4.6 minutes. Construct a confidence interval for the population variance $\sigma^2$ and the population standard deviation $\sigma$. Use a 95% level of confidence. Assume the sample is from a normally distributed population. What is the confidence interval for the population variance $\sigma^2$? (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) O A. With 95% confidence, you can say that the population variance is between and O B. With 5% confidence, you can say that the population variance is greater than O C. With 5% confidence, you can say that the population variance is less than O D. With 95% confidence, you can say that the population variance is between and What is the confidence interval for the population standard deviation $\sigma$? (Round to one decimal place as needed.) Interpret the results. Select the correct choice below and fill in the answer box(es) to complete your choice. (Round to one decimal place as needed.) O A. With 5% confidence, you can say that the population standard deviation is less than minutes. O B. With 95% confidence, you can say that the population standard deviation is between and minutes. O C. With 5% confidence, you can say that the population standard deviation is greater than minutes. O D. With 95% confidence, you can say that the population standard deviation is between and minutes.

7. Karl is a 78-year-old widower who lives in a senior-citizens apartment complex. Though he is reasonably healthy, both physically and mentally, Karl rarely gets out and typically does not take part in activities offered through the local senior citizens center. Rather, he mostly sits at home and broods. He rarely interacts with his neighbors in the apartment complex, and even his children and grandchildren avoid visiting him because all he does is complain about how bad his life has been.

Digital Design Design an FSM that has an input s and output f. The machine is a sequence detector that produces f = 1 when the previous four values of s were as follows: 0111 Otherwise, f = 0. Solve this in intel quartus and modelsim lite software. It should contain: \begin{itemize} \item State diagram of the FSM \item Block diagram of the design \item The Verilog program. \item The testbench program \item The simulation outputs \item Discussion of your design and the results that you obtained. \end{itemize}
