Which hypothesis is stated in the null form? Group of answer choices The math achievement scores from School A are significantly higher than the scores from School B. The perceptual-motor development of first-grade girls is higher than that of first-grade boys. There is a positive relationship between attitude toward school and achievement scores. There is no difference between the vocabulary scores of average- and high-ability students.

Do parents feel differently today than they did twenty years ago? Use the a=0.1 level of significance. *** Because npo (1-Po) = 199.7 less than 5% of the population size, and the sample can be reasonably assumed to be random, the 10, the sample size is requirements for testing the hypothesis are satisfied.
