how to solve this using salt:
Give as much information as you can about the P-value of a t test in each of the following situations. (Use technology to calculate the P-value. Round your answers to four decimal places.) (a) two-tailed test, df = 9, t = 0.77 (b) upper-tailed test, df = 10, t = −0.70 (c) lower-tailed test, n = 20, t = −2.40 (d) lower-tailed test, n = 20, t = −5.30 (e) two-tailed test, n = 40, t = 1.50
