1. Determine test statistic value:

Z = -1.19

2. Find the p-value using the standard normal distribution for a one-tailed test for( H_A: \mu < 85 ) :

\text{p-value} = P(Z < -1.19)

Using the Z-table or a calculator, we find:

\text{p-value} = 0.1170

Answer:

\text{p-value} = 0.1170

2. Find the p-value using the standard normal distribution for a one-tailed test for
