Ratios
A ratio is a comparison between two numbers of the same kind. It represents how many times one number contains another. It also represents how small or large one number is compared to the other.
Trigonometric Ratios
Trigonometric ratios give values of trigonometric functions. It always deals with triangles that have one angle measuring 90 degrees. These triangles are right-angled. We take the ratio of sides of these triangles.
Question

Include 5 steps to answer part A :)

10. The stimulant Ritalin has been shown to increase atten- tion span and improve academic performance in chil- dren with ADHD (Evans et al., 2001). To demonstrate the effectiveness of the drug, a researcher selects a sample of n = 20 children diagnosed with the disorder and measures each child's attention span before and af- ter taking the drug. The data show an average increase of attention span of Mp = 4.8 minutes with a variance of s = 125 for the sample of difference scores. a. Is this result sufficient to conclude that Ritalin significantly improves attention span? Use a one- tailed test with a = .05. b. Compute the 80% confidence interval for the mean change in attention span for the population.
