The area under the standard normal curve to the right of z = 1.43 can be found using standard normal distribution tables or a calculator that provides cumulative distribution function (CDF) values for the normal distribution.
First, we need to find the cumulative area to the left of z = 1.43. This value represents the probability that a standard normal random variable is less than 1.43. Typically, from standard normal tables, the value corresponds to approximately 0.9236.
To find the area to the right of z = 1.43, we subtract the area to the left from 1:
A = 1 – P(Z < 1.43) = 1 - 0.9236 = 0.0764.
Therefore, the area under the standard normal curve to the right of z = 1.43 is approximately 0.0764, or 7.64%.
