15.单选题 收藏 已标记 Let (C) be a random normal variable that characterizes the temperature in degree Celsius. Assume (C) has mean of 30.0 and standard deviation of 2.0. Let (F) be the corresponding temperature in degrees Fahrenheit given by F = 1.8×C ＋ 32. Which of the following statements is the best direct reflection of the location-scale invariance property of the normal distribution? A If mean of C were instead 0 with variance of 1, then C would be a standard normal B Standard deviation of F is 2.0 C Standard deviation of F is 3.6 D F is normally distributed 这道题答案不明白说的是啥，我自己的答案选择D，答案为啥去分析了C答案？？麻烦讲解一下？
