Answer #1

For the given table of coefficients, we can see for the independent variable Weight here the p-value as 0.8485 which is very high, therefore the variable is not significant here in explaining the variation in the dependent variable fuel economy.

Also, the 95% confidence interval given for weight contains 0, which means that the independent variable weight is not a significant variable in regression here.

Therefore the final conclusion here is that we are 95% confident that the independent variable weight is not significant in explaining the variation in the dependent variable fuel economy.
