In an analysis of two independent samples, log transformation has been applied to original data so that t-tools can be used. After transformation, both sample distributions appear to be bell-shaped. The sample mean difference of the log-transformed data between two samples is calculated to be 5.87. Then which of the following quantities should be used to estimate the ratio between population medians of original variables?

(a) 5.87

(b) log(5.87)

(c) exp(5.87)

(d) 5.87^e
