Malani is examining the following research question: Is there a mean difference in the weight of garbage thrown away per week by homeowners as compared to renters? Use the 'Garbage' dataset. "Weight" is a ratio level measurement scale variable. "Own_Rent" is a nominal level measurement scale variable. Conduct the the appropriate inferential statistical procedure at an alpha level of .05. Do NOT exclude any cases when conducting the test. Which one of the following is correct based on reviewing the assumptions?
A) Skewness and kurtosis statistics provide some evidence to suggest that homogeneity of variance is a reasonable assumption.
B) Skewness and kurtosis statistics provide some evidence to suggest that homogeneity of variance is NOT a reasonable assumption.
C) Skewness and kurtosis statistics provide some evidence to suggest that independence is a reasonable assumption.
D) Skewness and kurtosis statistics provide some evidence to suggest that independence is NOT a reasonable assumption.
E) Skewness and kurtosis statistics provide some evidence to suggest that normality is a reasonable assumption.
F) Skewness and kurtosis statistics provide some evidence to suggest that normality is NOT a reasonable assumption.

Skewness and kurtosis statistics are measures used to assess the normality of the distribution of a variable. In this context, if the skewness and kurtosis values are within acceptable ranges, they suggest that the assumption of normality for the variable "Weight" is reasonable. Homogeneity of variance and independence are assessed through different tests and assumptions, not directly through skewness and kurtosis.
