What percentage of data would you predict would be between 25 and 50 and what percentage would you predict would be more than 50 miles? Use the Week 4 spreadsheet again to find the percentage of the data set we expect to have values between 25 and 50 as well as for more than 50. Now determine the percentage of data points in the dataset that fall within each of these ranges, using same strategy as above for counting data points in the data set. How do each of these compare with your prediction and why is there a difference? Predicted percentage between 25 and 50: ________________________ Actual percentage: Predicted percentage more than 50 miles: Actual percentage: ___________________________________________ Comparison ____________________________________________________ Why? __________________________________________________________ Drive: 44 20 88 6 71 42 76 63 61 63 84 28 55 33 88 80 86 83 5 85 25 25 54 54 81 73 29 76 78…

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…
this class is so confusing please help ! I need to pass! Psychology researchers have demonstrated that memory is usually improved by studying material on multiple occasions rather than one time only (distributed practice effects). A recent study examining this effect studied two different delay intervals. Group 1 had a one-day interval between study sessions and group two had a one-week gap between study sessions. Results for each study condition are presented below: One-Day Gap n = 20 M = 26.4 SS = 395 One-Week Gap n = 20 M = 29.6 SS = 460. Do the data indicate a significant difference between the two study conditions? Evaluate this hypothesis at the .05 significance level? · State your hypotheses · State the critical t-value · Calculate the t-value for the sample mean difference · State your conclusion about the null hypothesis Show all calculations.
