O Specific differences between pairs of means are not known when a significant result is found O The difference between three or more means will be examined O The Type I error rate is inflated automatically compared to the t test for independent samples even if you use the same alpha O Two estimates of the population variance are comparedQuestion 14 2 pts A researcher was interested in how watching videos about a particular activity affects the desire to attend college among high school students.High school juniors planning to attend college were randomly assigned to view one of four videos emphasizing athletics, social life, scholarship, or artistic/cultural opportunities at a particular college. After viewing the videos, the participants took a test of their desire to attend this college with the following results (means and standard deviations are provided except for the last group): Athletics: M=66.75, s=6.55, N=5 Social Life: M=80.25, s=5.44, N=5 Scholarship: M=76.75, s=3.40, N=5 Art/Cultural: Raw Scores: 76, 71, 69, 65, 68 What is the research hypothesis? O Watching videos emphasizing a particular activity will affect the desire to attend college O Watching videos emphasizing a particular activity will have no effect on the desire to attend college O Watching videos emphasizing a particular activity will decrease the desire to attend college O Watching videos emphasizing a particular activity will increase the desire to attend collegeQuestion 15 2 pts For the following problem, please round to two decimal places: In an analysis of variance with a within-group variance estimate of 18.99 and a between-group variance estimate of 18.09, the F ratio is
