Applet Exercise Refer to Example 7.6. Suppose that T has a t distribution with 5 df.

Use the applet Student’s t Probabilities and Quantiles to find the exact probability that T is greater than 2.Use the applet Student’s t Probabilities and Quantiles to find the exact probability that T is less than −2.Use the applet Student’s t Probabilities and Quantiles to find the exact probability that T is between −2 and 2.Your answer to part (c) is considerably less than 0.9544 = \(P(-2 \leq Z \leq 2)\). Refer to Figure 7.3 and explain why this is as expected.
