How do we calculate the p value of a test where the alternative hypothesis is that the mean greater than the assumed value?

Find the probability that we would see a value less than the test statistic on the standard normal distribution.

Find the probability of seeing a value greater than the test statistic on the standard normal distribution.

Find and to add together the probability of seeing a value greater than the test static and the probability of seeing a value less the negative of the test statistic or (vice versa if the z value is negative)

A survey of 1025 adults found that 113 of them, or 11%, said they or a household member had been a victim of a computer or internet crime on their home computer in the past year.

The health of employees is monitored by periodically weighing them in. A sample of 54 employees has a mean weight of 183.9 lb. Assuming that ? is known to be 121.2 lb, use a 0.10 significance level to test the claim that the population mean of all such employees weights is less than 200 lb.
