Final answer:
To find the area in the right tail more extreme than z=-1.26, use the cumulative probability from the z-table for z=1.26 and subtract it from 1, which gives us approximately 0.104.
Step-by-step explanation:
To find the area in the right tail more extreme than z=-1.26 in a standard normal distribution, we look up the area to the left of z=-1.26 using a z-table or a statistical calculator. The table or calculator provides the cumulative probability up to that z-score. Since the normal distribution is symmetric about the mean, the area to the right of z=-1.26 will be the same as the area to the left of z=1.26. Once we have that value, to get the right tail area we subtract it from 1. Using a standard normal distribution table, the area to the left of z=1.26 is approximately 0.896. Therefore, the area in the right tail more extreme than z=-1.26 would be 1 - 0.896, which equals 0.104.
