Z scores, Z statistics, p-value and APA format

Given the research scenario, data points, set of population parameters and alpha set at p = .05, generate the correct:
- Pair of hypotheses for each data point
- A z statistic and p value for each data point
- Decision about the null hypothesis for each data point
- APA-formatted statement of results for each data point

Please report z scores to two decimals and p values to three decimals. If the p value is less than .001, report it as p < .001.
