It is known that for right-handed people, the dominant (right) hand tends to be stronger. For left-handed people who live in a world designed for right-handed people, the same may not be true. To test this, muscle strength was measured on the right and left hands of a random sample of 15 left-handed men and the difference (left-right) was found. The alternative hypothesis is one-sided (left hand stronger). The resulting t-statistic was 1.80. This is an example of:

Explanation:
Detailed explanation-1: -Conclusion: We concluded that the dominant hand is significantly stronger in right handed subjects but no such significant difference between sides could be documented for left handed people.
Detailed explanation-2: -They found no difference in IQ levels among left-and right-handed people, but left-handers appeared to be more likely to have an intellectual disability. However, this study indicated that people who were intellectually gifted or following typical development were also just as likely to be left-handed.
