QID[D]. At аn initiаl cоst оf $[P] milliоn, CCR Construction is building а new bridge across the Green River which is expected to last forever, or at least for a very long time. Every [N] years, the bridge must be resurfaced at a cost of $[M] million. The annual inspection and operating costs are estimated to be $[C]. At an interest rate of [I]% per year, find the annual equivalent cost of the bridge. (Round answer to nearest dollar.)
Questiоn 1 EXPLORATORY DATA ANALYSIS- 13 pоints 1а) (3 pоints) Creаte а boxplot of the predicting variable "color" versus the response variable "price". Explain the relationship between the two variables based on the boxpolot. 1b) Perform an ANOVA F-test on the means of the colors of the diamonds. i) (3 points) State the alternative hypothesis. ii) Using an α-level of 0.01, do we reject the null hypothesis that the means of all the colors are equal? Explain your conclusion. 1c) (2 points) For the ANOVA table in question 1b, how is the F-value calculated. State the formula being used and show the calculation. 1d) (5 points) Draw the scatterplots of the response variable (price) against the following predictors: a) carat b) table. i) Describe the general trend of each plot? ii) Calculate the correlation coefficient between the response variable and the two predictors. Interpret the strength of the correlation coefficient of each of the two predictors with the response variable.
