COMPLETE THE TABLE FOR THE PROBLEM
1. Research has shown that IQ scores have been increasing for years (Flynn, 1984, 1999).
The phenomenon is called the Flynn effect and the data indicate that the increase appears
to average about 7 points per decade. To examine this effect, a researcher obtains an IQ
test withinstructionsforscoringfrom 10yearsago and plans to administers the test to a
sample of n = 25 of today's high school students. Ten years ago, the scores on this IQ test
produced a standardized distribution with a mean of μ = 100 and a standard deviation o=
15. If there actually has been a 7-point increase in the average IQ during the past 10 years,
then find the power of the hypothesis test for each of the following.
a. The researcher uses a two-tailed hypothesis test with a = .05 to determine if the
data indicate a significant change in IQ over the past 10 years. [one table]
1. Research Hypothesis
Null hypothesis: The... has no significant effect on the DV
Alternative hypothesis: The... has a significant effect on
the DV....
2. Statistical Hypothesis
3. Level of Significance
Alpha .001, .01, or .05
4. Critical Value
(depends on the z-value, refer to unit normal table and
computation)
5. Decision Rule
"Fail to reject (accept) or reject"
6. Statistical Conclusion
