For problems 4-7, you are asked to calculate a confidence interval. Your calculation should include all intermediate values. Intermediate values include: \\ For confidence intervals based on $\sigma_X$: z, $\sigma_X$ For confidence interval based on $S_X$: df, t, $S_X$ For confidence intervals for proportions: z and $S_p$ 4. In a sample of 25 college students, the wait time for an advising appointment was 13.2 days (s = 3.2). a. Calculate a 95% confidence interval for advising wait time. Be sure to show all relevant intermediate values. b. Interpret the meaning of this confidence interval. 5. A recent Pew poll of American adults found that 63% of the sample (n = 8,480) had very little or no confidence in the federal government. a. Calculate a 99% confidence interval for lack of confidence in the federal government. Be sure to show all relevant intermediate values. b. Interpret the meaning of this confidence interval. 6. A local brewery sampled their customers on a recent afternoon (N=20) and found that the average number of drinks consumed was 2.5 (s = 2.1). a. Calculate a 90% confidence interval for the average number of drinks consumed per customer. Be sure to show all relevant intermediate values. b. Interpret the meaning of this confidence interval. 7. For Problem Set 1, you worked with data on the time that individuals have been in their jobs. From a sample of 139,890 respondents, the average time in a job was 5.9 years (s = 6.27). a. Calculate a 95% confidence interval for the average job tenure. Be sure to show all relevant intermediate values. b. Interpret the meaning of this confidence interval.

Can someone thoroughly explain how to solve part c and d? 5. [6/10 Points] DETAILS PREVIOUS ANSWERS STATSBYLO116.2B.010.CHDS.S. MY NOTES PRACTICE ANOTHER Scientists are interested in the placebo effect on adults with arthritis. They randomly choose 15 adults with arthritis and give them 2 treatments - effective drug and placebo for 1 week at different times. At the end of each week, the scientists ask the participants to rate their arthritic pain level on a scale of 1-5, where 1 is little pain and 5 is a lot of pain. The researchers then take the difference of their pain levels (effective drug - placebo). The data are below: 0, 1, -2, 2, 0, -1, 3, 1, 2, -1, 0, 1, -2, -1, -6 USE SALT a) Find the 5-number summary for the difference of arthritic pain levels: Minimum = 6 Qi Median Maximum b) One of the conditions for inference for population mean difference of paired data is normality. Outliers within a data set cast a shadow of doubt upon the normality of the population distribution. Use the 5-number summary calculated in part (a) to determine if there are any outliers in the data set. Which of the values, if any, is an outlier according to the outlier rule? Select all that apply. -6 2 3 None of the data values are outliers c) Despite your answer to part b, assume the conditions for inference have been met. Using the sample standard deviation S = 2.18, calculate a 95% confidence interval for the true mean difference of arthritic pain levels. Use a table or technology. Round your answers to two decimal places. [-1.54, x, A confidence interval is of the form Point estimate Margin of Error.874] X A confidence interval is of the form Point estimate Margin of Error. d) What would happen if the scientists increased the sample size? Continue to assume that the conditions for inference have been met. Using the sample standard deviation of s = 2.8, and the same point estimate, calculate a 95% confidence interval for the true mean difference of arthritic pain levels if a sample size of 20 were used. (Use a table or technology. Round your answers to two decimal places.)

Question 3 15 pts Given are the following expressions from another 8QAM constellation. What would be the exact expression for probability of bit error in terms of average energy per bit? $E_{s8} = 3d^2$, $P_{e8} = \frac{5}{7}Q - \frac{3}{16}Q^2$ $P_{bM} = \frac{5}{21}Q \left(\sqrt{\frac{E_b}{4N}}\right) - \frac{1}{16}Q^2 \left(\sqrt{\frac{E_b}{4N}}\right)$ $P_{bM} = \frac{5}{21}Q \left(\sqrt{\frac{E_b}{2N}}\right) - \frac{1}{16}Q^2 \left(\sqrt{\frac{E_b}{2N}}\right)$ $P_{bM} = \frac{5}{21}Q \left(\sqrt{\frac{E_b}{8N}}\right) - \frac{1}{16}Q^2 \left(\sqrt{\frac{E_b}{8N}}\right)$
