Question
Indicate the appropriatestatistical test for analyzing the relationship between theindependent and dependent variables. Assume that the underlyingassumptions of the tests have been satisfied. An investigator examined the effect of practice onproblem-solving performance. Study participants were randomlyassigned to one of two conditions. Seventy-five individuals triedto solve 30 problems after having a 10 minute practice session on asimilar set of problems. A different 75 individuals tried to solvethe same 30 problems, but with no practice session. The averagenumber of correct solutions was compared for participants in thepractice versus the no-practice conditions.

the test which should be used is two sample z test (i.e standardized normal distribution) because the sample size is big (i.e more than 30)
