Answer the last question:Interpret the results =You are given the sample mean and the population standard deviation. Use this information to construct the 90%and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidenceintervals.From a random sample of 37 business days, the mean closing price of a certain stock was $112.50. Assume thepopulation standard deviation is $9.71.The 90% confidence interval is (109.87, 115.13).(Round to two decimal places as needed.)The 95% confidence interval is (.109.37, 115.63).(Round to two decimal places as needed.)Which interval is wider? Choose the correct answer below.The 95% confidence intervalThe 90% confidence intervalInterpret the results. You are given the sample mean and the population standard deviation. Use this information to construct the 90%and 95% confidence intervals for the population mean. Interpret the results and compare the widths of the confidenceintervals.From a random sample of 37 business days, the mean closing price of a certain stock was $112.50. Assume thepopulation standard deviation is $9.71.Interpret the results.OA. You can be certain that the population mean price of the stock is either between the lower bounds ofthe 90% and 95% confidence intervals or the upper bounds of the 90% and 95% confidence intervals.B. You can be 90% confident that the population mean price of the stock is outside the bounds of the 90%confidence interval, and 95% confident for the 95% interval.OC. You can be certain that the closing price of the stock was within-the 90% confidence interval forapproximately 33 of the 37 days, and was within the 95% confidence interval for approximately 35 of the37 days.OD. You can be 90% confident that the population mean price of the stock is between the bounds of the 90%confidence interval, and 95% confident for the 95% interval.

It is given that • The 90% confidence interval is CI = ( 109.87, 115.13 )• The 95% confidence…

Answered: Interpret the results. OA. You can be…

Many institutes, departments, and recruitment committees are using citations as part of the assessment process involved in making new appointments. By going through scientific databases like Scopusselection panels can check if a candidate’s work is making an impact by being cited by other researchers in their field. How does the scientific community measure how "good" or "great" a journal or an author is? How do you determine the "impact" of an author's work? The most 2common metric to track an author's impact is ask how often they are cited. The following table presents the number of citation on research publications of two Management Science professors over a period of 17years, 2005 to 2021, data taken from Google Scholar. The objective of this assignment is to find a suitable forecasting method (moving average, exponential smoothing, and/or simple linear regression model) to predict near future citation of a researcher. (a) For each professor, develop a scatter diagram on his…
