Your Question: 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. The data is below: 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, 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…

Topic: Understanding the Data Around Us Instructions: 1. Show your complete solutions and highlight/box your final answers. 2. If you will use Excel, simply get the important values in the Data Analysis and write/type them in your paper. You don't need to include the entire results in your solutions, just get the essential values. Question: 1) A recent study stated that if a person chewed gum, the average number of sticks of hum he or she chewed daily was 8. To test the claim, a researcher selected a random sample of 36 gum chewers and found the mean number of sticks of gum chewed per day was 9. The standard deviation of the population is 1. At , a = 0.05 is the number of sticks of gum a person chews per day actually greater than 8? State the correct interpretations and conclusion. A. State the hypothesis. B. Find the critical value(s). C. Compute the test value. D. Make the decision. E. Summarize the results.
