Given p( z > a) =0,7422 Find a

To find the value of a when p(z > a) = 0.7422, we can use a standard normal distribution table or calculator.

Using a standard normal distribution table, we can look up the value of z that corresponds to a probability of 0.7422. The closest value we can find in the table is that for a probability of 0.7420, which corresponds to a z-value of approximately 0.61.

Therefore, a ā‰ˆ 0.61.
