To find c, you need to use a standard normal distribution table or a calculator that can compute the inverse of the cumulative distribution function (CDF) for a standard normal distribution.
Using a standard normal distribution table, you can find the closest probability value of 0.8018. In this case, the closest value in the table is 0.8019, found in the row corresponding to z = 0.8 and column corresponding to the second decimal place of 0.01.
Therefore, c is approximately 0.8.
For a standard normal distribution, find:
P(z < c) = 0.8018
Find c rounded to two decimal places.
