Current Attempt in Progress Computer output from a regression analysis is provided. Coefficients Estimate Std. Error t value Pr(>|t|) (Intercept) 7.2960 14.5444 0.502 0.62200 1.6370 0.5453 3.002 0.00765 X Use the p-value for testing if the slope in the population is different from zero (and a 5% significance level) to make a clear conclusion about the effectiveness of the model. There is very strong evidence that the population slope differs from zero, and thus is an effective model for predicting this response variable. There is not enough evidence that the population slope differs from zero, and thus is not an effective model for predicting this response variable. Save for Later Attempts: 0 of 1 used Submit Answer

[Statistics] Use R or RStudio Context of the problem:Fire damage in the United States amounts to billions of dollars, much of it insured. The time taken to arrive at the fire is critical. This raises the question, Should insurance companies lower premiums if the home to be insured is close to a fire station? To help make a decision, a study was undertaken wherein a number of fires were investigated. The distance to the nearest fire station (in miles) and the percentage of fire damage were recorded. Here is the data set: Distance    Percent7.5    688.3    666.2    341.6    305.6    706    624.3    478.1    725.7    400.3    531.6    182.5    485.8    535.3    486.3    643.4    526.2    613.2    346.3    656.1    664.6    336.7    760.5    343.2    465.3    555    334.8    466.4    490.2    174.9    476.2    637.6    696.6    542.9    522.1    434.8    358.1    581.2    54.6    464    576.1    400.8    395.9    426.5    626.5    527.5    767.2    676.7    454.1    234    334.8    594…
