Q 1[10 pоints]. The fоllоwing dаtа аre diameters (in cm) of two types of pine trees. Type I: 37.1 37.8 38.8 41.1 34.8 34.0 33.6 35.1 35.0 36.3 33.2 38.7 Type II: 32.4 40.8 31.8 27.1 36.6 25.0 28.7 28.3 30.9 27.6 33.2 Exam the data graphically using side by side boxplots and discuss your findings. What are the appropriate null and alternate hypothesis to compare the two types of trees? Perform the hypothesis tests that you listed in (b). Report test statistics & p-value. Summarize your conclusion Find and interpret 95% confidence interval for the difference between the two means List and verify the assumptions required for (c )and (d). Q2[5 points]. A student hypothesizes that freshman, sophomore, junior and senior college students have different attitude towards obtaining arts degrees. Based on his prior knowledge, he expects that the effect size is about 0.30. For a power of 0.80 at significance level 0.05, what should be the total sample size. For a higher power 0.90, but same significance level What would be the required sample size? Q3[15 points]. Use PimaIndiansDiabetes data in library(mlbench). Divide the data set into train and test data (random selection, 80%: 20%). The goal here is to model and predict if a given sample is diabetes Class ‘positive (pos)’ or ‘negative (neg)’. A. Fit a logistic regression model for the above purpose. Interpret your results. Use the model to predict both using training data and test data. Prepare confusion matrix and compare training accuracy and testing accuracy. B. Use Linear Discriminant Analysis for classification. Use the model to predict both using training data and test data. Prepare confusion matrix and compare training accuracy and testing accuracy. C. Which method gives you better results. Explain. Q4[10 points]. Use the moth-trap data Click here to get the data We would like to see whether there is any Factor A - 'location effect' on the number of moths Factor B - 'Type of Lure' effect on the number of moths and Interaction effect on the number of moths. Perform required analysis and report your results with necessary tables. Verify any assumptions that are needed for the analysis you did. .
