##### When a 10.0 g sample of KOH was dissolved in 100 g of water in acoffee-cup calorimeter, the temperature increased by25.0 oC. Assume that the total heat capacity of thecalorimeter was 418 J/oC. Calculate the heat,the Î”Î”H, for dissolving KOH, in kJ/mol. Use 56.1 for the molarmass of KOH. Be careful of the sign.

##### Estradiol is a sex hormone. It not only has a critical impact onreproductive and sexual function, but it also affects other organs,including bones. Using the dataset "estradl.dta," (under resources,homework files, estradl.dta) run a regression using Body Mass Index(BMI) as the independent variable, and estradiol levels (ES_1) asthe dependent variable. Save the standardized residuals,unstandardized and standardized predicted values, and the mean andindividual prediction intervals. After
