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].
