The lower tail probability corresponds to the area under the curve to the left of the given value. Sometimes you will want to work with areas other than the lower tail. It is easy to convert from lower tail to another area as long as you keep in mind that the total area under the curve is equal to 1, and the Normal and the Student’s T distributions are symmetrical.

Figure 18 The desired area is to the right of 1.2 and to the left of - 1 .2. Since normal distributions are symmetrical, and the areas are the same, you can calculate the lower tail area and simply multiply by 2.

Figure 19 The given area is 0.95. The area not included is 1-0.95/2 = 0.025. Since the normal distribution is symmetrical, half of the desired area is in the lower tail, .05/2=.025.
