Question

Research has shown that losing even one night’s sleep can have a significant effect on performance ofcomplex tasks such as problem solving (Linde &Bergstroem, 1992). To demonstrate this phenomenon,a sample of n=25 college students was given aproblem-solving task at noon on one day and again atnoon on the following day. The students were notpermitted any sleep between the two tests. For eachstudent, the difference between the first and secondscore was recorded. For this sample, the studentsaveraged MD=4.7 points better on the first test with avariance of s2=64 for the difference scores.

a.Do the data indicate a significant change in problem-solving ability? Use a two-tailed test with a= .05.

b.Compute an estimated Cohen’s dto measure thesize of the effect
