Question

A researcher theorizes that students at a particular university differ in intelligence from the average IQ of 100. The researcher computes the 95% confidence interval for the mean of this population. Four possible results are shown below.

Result 1: 91.6–109.4
Result 2: 99.1–116.9
Result 3: 101.2–119.0
Result 4: 112.7–130.5


Which result most strongly supports the researcher’s theory?

result 3.

result 4.

both result 3 and result 4 provide equally strong support for the researcher’s theory.

neither result 3 nor result 4 supports the researcher’s theory.

result 3.

result 4.

both result 3 and result 4 provide equally strong support for the researcher’s theory.

neither result 3 nor result 4 supports the researcher’s theory.

Explanation / Answer

Given sample mean=100

sample size and population standard deviation is unknown

Hence we can not find the confidence interval.

neither result 3 nor result 4 supports the researcher’s theory.
