Solve the following:
Q1: 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
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.
Q2: µ = 100 ; σ =30

Which child or children, if any, appeared to come from a significantly different population than the one used in the null hypothesis?
What happens to the "significance" of each child's data as the data are progressively more dispersed?
