For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.

What is Standard normal distribution?

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

In order to calculate the value of the P(z≤0.42), we need to check the value of 0.42 in the z-table, As the Z-table is already given and in the table, the value of z is 0.6628, therefore,

[tex]P(z\leq 0.42)\\\\=0.6628 \approx 66\\\\= 66\%[/tex]

Hence, For a standard normal distribution, the approximate value of P(z≤0.42) is 66%.
