Explanation / Answer

Solution :

Given that,

z = 1.66

This is the right tailed test

Using standard normal table,

P(Z > 1.66) = 1 - P(Z < 1.66)

   To see the z value 1.6 in the column and 0.06 in the row of the standard normal table the corresponding probability is 0.9515 .

P(Z > 1.66) = 1 - P(Z < 1.66) = 1 - 0.9515 = 0.0485

P-value = 0.0485
