Assessment records indicate that the value of homes in a small city is skewed right, with a mean of $X and standard deviation of $Y. To check the accuracy of the assessment data, officials plan to conduct a detailed appraisal of homes selected at random. Using the 68-95-99.7 rule, draw and label an appropriate sampling model for the mean value of the homes selected.
a) Create a normal distribution model with mean $X and standard deviation $Y.
b) Construct a positively skewed distribution model with mean $X and standard deviation $Y.
c) Develop a negatively skewed distribution model with mean $X and standard deviation $Y.
d) Establish a uniform distribution model with mean $X and standard deviation $Y.
