Hypothesis Testing and Inference

Table 3

µ = 100 seconds and σ = 30

Child	Mean seconds of concentration in an experiment of reading	z-score	p-value
1	75	-0.83
2	81	-0.63
3	89	-0.37
4	99	-0.03
5	115	0.50
6	127	0.09
7	138	1.27
8	139	1.30
9	142	1.40
10	148	1.60

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?

Provide a formal APA statement of conclusion for each child.
