In order to see whether mood affects reaction times in a cognitive task, researchers have a group of 6 participants perform the same attention task 3 times. Before each task, the participants are shown images and statements that induce a certain mood: sad, happy, neutral. Calculate the SS-Between Subjects value using this data. (Be sure to round answer to second decimal place). Sub Sad Happy Neutral A 35 60 55 B 40 55 50 C 40 65 60 D 30 65 40 E 25 75 60 F 20 65 45

A psychologist believed that as children get older, they engage in more “inactive activities” such as playing computer games, watching TV and surfing the internet. She collected data from 10 children. She recorded the age of each child and the amount of activity (in hours) the child engaged in per week.  Age Activity 7 4.3 9 3.2 10 1 13 1.5 12 1.2 15 0.8 9 3 12 4 15 1.5 14 1.9   Using excel, obtain a scatterplot of the data. Discuss the relationship between age and activity based on the scatterplot. Using excel, obtain the simple linear regression linear regression line predicting activity from age. Interpret the intercept and slope of the regression line. By hand, predict the amount of activity for age = 14. By hand, calculate the residual for age = 14 Using excel output, test the null hypothesis that the slope coefficient is zero using the p-value approach. Write one sentence interpreting the meaning of this result. Make sure to report the test statistic…
