Can moving their hands help children learn math? This question was investigated in a study. Eighty-five children in the third and fourth grades who did not answer any questions correctly on a test with six problems of the form 3 + 2 + 8 = ___ + 8 were participants in an experiment. The children were randomly assigned to either a no-gesture group or a gesture group. All the children were given a lesson on how to solve problems of...
SCENARIO: A small hospital uses a standardized test to measure depression. The psychometric properties of the test are Cronbach alpha of .48 and a test-re-test of .25. The test has a concurrent validity with another well-used test of .50. With so many current concerns of depression in adolescent girls, a nurse decides to conduct a study to determine if a nationally acclaimed intervention program for depression, Live Happy, could reduce the incidence of depression. The nurse develops a proposal that...
1. The average amount parents and children spent per child on back-to-school clothes in Autumn 2010 was $527. Assume the standard deviation is $160 and that the amount spent is normally distributed. What is the probability that the amount spent on a randomly selected child is more than $700? (Round to four decimal places) What is the probability that the amount spent on a randomly selected child is less than $100? (Round to four decimal places) What is the probability...
