MATH233 Unit 4 Individual ProjectNAME (Required): _____________________________Dr. Claude Shannon (1916 – 2001), “the father of information theory,” observed that the maximum error-free capacity in bits per second (bps) obtainable in a communication channel can be found by the Shannon-Hartley equation:bits per secondAbove, , is the bandwidth of the channel in Hertz and is the signal-to-noise ratio of the channel. Since 0 does not make sense in this situation, assume that the formula below is correct:This is a “pure” number with no unit labels on it. The value of is called Shannon’s Capacity Limit or channel capacity. This is the theoretical upper limit for the bits per second through the channel with a specific value and a specific given channel frequency bandwidth, , in Hz. Be sure to show your work details for all calculations and explain in detail how the answers were determined for critical thinking questions. Round all value answers to three decimals.1.In this assignment you will use the following version of the Shannon-Hartley equation.bits per secondIn the table below, based on the first letter of your last name, choose a value from the stated range for the bandwidth, , for your communication channel’s bandwidth. For example, if your last name begins with A-F, and you choose 100,000,000 for your value of B, then your channel capacity function for this assignment would be:bits per secondWrite your maximum error-free channel capacity function below the table.. First letter of your last name Possible values for in Hz A–F 100,000,000 – 125,000,000 G–L 150,000,000 – 175,000,000 M–R 200,000,000 – 225,000,000 S–Z 250,000,000 – 275,000,000 State your channel capacity function here:2.Calculate the derivative of your channel capacity function with respect to What is the meaning of in the context of this channel capacity scenario?Show your work details.3.Generate a graph of this function using Excel or another graphing utility. (There are free downloadable programs like Graph 4.4.2 or Mathematics 4.0; or, there are also online utilities such as this site and many others.) Insert the graph into the Word document containing your answers and work details. Be sure to label and number the axes appropriately.4.For your function from question #1 what is the instantaneous rate of change in maximum error-free channel capacity with respect to SNR, for ? Show your work details.5.What is the equation of the tangent line to the graph of , when ? Show your work details.6.In general, the Shannon-Hartley equation applies to any communication channel with a known bandwidth.For example, a device like a cable modem may have a very high SNR (> 1000) but a fairly narrow bandwidth.The Data Over Cable Service Interface Specification (DOCSIS 3.0) requires that the downstream per channel bandwidth of a compliant cable modem must be either 6 MHz or 8 MHz wide. Research the Library or the Internet to find a reasonable downstream bandwidth in MHz of a commercially available brand of cable modem. State the name of the commercially available cable modem you found and give the reference where your found the cable modem information. Use that bandwidth together with an SNR = 1023 to find the channel capacity of the cable modem. Whether you have cable Internet service or not, are you getting this type of downstream service from your Internet Service Provider?What justification do you give for this answer?Show your work details on all calculations.References Desmos.

Multiple Regression Analysis
*** Please note: SPSS Statistics must be used to answer these questions. The .sav and .spv files must be submitted in addition to DETAILED answers for each question including the supporting SPSS outputs included for each answer. If possible, please explain the steps taken to get each answer. Multiple Regression AnalysisThe purpose of this assignment is to apply multiple regression concepts, interpret multiple regression analysis models, and justify business predictions based upon the analysis.For this assignment, you will use the "Strength" dataset. You will use SPSS to analyze the dataset and address the questions presented. Findings should be presented in a Word document along with the SPSS outputs.The compressive strength (Y) of concrete is influenced by the mixing proportions and by the time that it is allowed to cure, although the exact relationship between the strength and the components is unknown. The provided data includes the results of n = 1030 concrete strength experiments that include the following:Strength (in MPa): The compressive strength of the concrete.Age (in days): The number of days the concrete was allowed to cured.Coarse_Aggregate (in kg/m3): The proportion of coarse aggregate in the mix.Fine_Aggregate (in kg/m3): The proportion of fine aggregate in the mix.Cement (in kg/m3): The proportion of cement in the mix.Slag (in kg/m3): The proportion of furnace slag in the mix.Superplasticizer (in kg/m3): The proportion of plasticizer in the mix.Water (in kg/m3): The proportion of water in the mix.Ash (in kg/m3): The proportion of fly ash in the mix.Part 1:Derive various transformations of compressive strength to determine which transformation, if any, results in a variable that most closely mimics a normal distribution. To do this, plot Q-Q plots after each transformation listed below, and decide which one should be used to build a multiple linear model. Explain your answer and provide the SPSS output as an illustration.Strength (no transformation)Square root of StrengthSquared Strength(Natural) Log of StrengthReciprocal of StrengthPart 2:Based on the transformation selected in Part 1, build a multiple linear regression model with all eight predictors.Use t-tests to determine if any of the predictors significantly affect the compressive strength of concrete. Explain why each variable should or should not be included in the model. Assume α = 0.05. Show the appropriate model results to explain your answer.If any predictors from question 1 are found to be not significant, remove them and re-run the model to create a reduced model (RM). Are all the remaining variables still statistically significant? Show the appropriate model results to explain your answer.Based on the RM, should there be concern about multicollinearity among the predictors selected? Show the appropriate model results to explain your answer.After fitting the RM, derive the residual plot (standardized residuals vs. standardized predicted values) and normal probability plot. Interpret each plot.What is the coefficient of determination, R2, of the RM? How would you interpret the R2?Based on the RM, what would be the new estimated compressive strength that is currently 50 MPa, after a 10-day increase in curing time? Assume all other predictors are held constant.How would you interpret the intercept (constant) in the RM? Does the interpretation make sense given the data you used to build the RM?Part 3:Given the following components and aging time below, what is the estimated compressive strength based on the RM?Age: 50 daysCoarse_Aggregate: 900 kg/m3Fine_Aggregate: 600 kg/m3Cement: 300 kg/m3Slag: 200 kg/m3Superplasticizer: 7 kg/m3Water: 190 kg/m3Ash: 70 kg/m3Part 4:What is a 95% confidence interval of the estimate in Part 3? How would you interpret the 95% confidence interval? (Hint: Use the SPSS scoring wizard to address this question.)
