Question: Lesley investigated the relationship between handedness and motor competence in preschool children. Random samples of 41 right-handers and 41 left-handers were administered several tests of motor skills, yielding the means and standard deviation shown in the following table. Do the data show any difference between handedness and motor skills in preschool children? For this problem, do not assume that the two populations have the same population variance

  1. State between the left- and right-handed preschool children based on the experiment.
  2. Perform a nonpooled (unknown \(\sigma_{1}\) and \(\sigma_{2}\) are not assumed equal) t-test at 5% significance level by comparing critical value and the test statistic.
