Without the actual values or specific data, it is impossible to calculate the confidence interval directly. However, based on the answer choices, we can assume that the slope estimate is between 10 and 20. Therefore, the range of the confidence interval should have a similar magnitude.

Choice A: 11.98 to 16.13 - This range is too narrow and does not span a wide enough range to be the correct answer.

Choice B: 10.67 to 17.45 - This range is a bit wider than Choice A and could be a potential answer. However, it is not as wide as Choice D.

Choice C: 9.57 to 18.54 - This range is the widest of all the choices and could be a potential answer. However, it may be too wide and not precise enough to be the correct answer.

Choice D: 9.64 to 18.46 - This range is wide enough to encompass the potential values of the slope estimate while also being specific and precise. Therefore, the correct answer is D.
