Question: Explain why the distribution of t ratios calculated from small samples drawn from the exponential pdf, fY(y) = ey, y 0, will be skewed

Explain why the of t ratios calculated from small samples drawn from the exponential pdf, fY(y) = e−y, y ≥ 0, will be skewed to the left [recall Figure 7.4.6(b)]. [What does the shape of fY(y) imply about the possibility of each yi being close to 0? If the entire sample did consist of yi ’s close to 0, what value would the t ratio have?]
