Using the data in the image, I need to find the regression using the data analysis in excel. I don’t know which should be the input x or the input y range. Smoking data is to be with each of the remaining four data depicting the types of cancer. Can anyone help?
# 1 Given the data as shown in the table below X Y 3.8 | 9.8 2.5 8.8 4.1 9.7 0.9 7.5 2.4 9.6 The correct equation of the "Best-Fit"/Regression line associated with the given data above would be Oŷ = 0.6742z + 7.2326 Oy = 0.6742z + 7.2326 Oy = 0.67427 + 7.2326 Oŷ = 0.67427 + 7.2326 Oŷ = 7.23262 + 0.6742 Note: Round all coefficients to four decimal places.
Consider the data on climate change below: Variable Intercept CO2 Coefficient SE(Coeff) 0.1584 0.0004 T-ratio -20.1 22.1 P-value |-3.17933 <0.0001 <0.0001 0.00992 s=0.0885 with 58-2=56 degree of freedom. R squared = 89.7%. The response variable is temperature. %3D Then CO2 level for this data is 352.6ppm. a) Find a 90% confidence interval for the mean global temperature anomaly if the CO2 level reaches 450ppm. b) Fina a 90% prediction interval for the mean global temperature anomaly if the CO2 level reaches 450ppm. c) The goal of the Paris climate agreement is to a temperature anomaly of about 1.3degC in our data. If CO2 level do reach 450ppm, would this be a plausible value?
2. The data below obtained from the experiment: 1.5 1.8 2.4 2.7 3.2 3.6 f(a) 0.7555 0.6206 0.5052 0.4812 0.4498 0.4337 This data can be fitted to the curve y where C and D are C + Dr constants. a. Show that the curve above can be written as 1 = D+ b. Hence, by using the least squares linearization process, determine the value of C and D. Start your calculation with S =E( -Y(X.)) where S is the total squares error. c. Estimate the value of f(2.5) based on the results obtained in part (b).
The image shows the estimation of the model with quarterly car sales in the U.S. from 1975 to 1990. Based on the parameter estimates, what is the predicted effect of a 10% increase in price on the number of cars sold? What would be the effect of that price increase on the value of car sales?
