Order: Penicillin V Potassium 125 mg PO q6h for a child weighing 36 lb. The recommended dose PO for a child is 25-75 mg/kg/day divided q6-8hr. Available: Penicillin V Potassium oral solution 250 mg per 5 mL Determine if the dose ordered is safe. If the dose is safe, calculate the number of mL the nurse should administer.  Is the dose safe, type yes or no [safe]. The nurse should administer [volume] mL.

Q2 Logistic Regression model (Use trainData for this question) (30 points) ( 5 points) a) Create a logistic regression model using Completed as the response variable and the following predicitng variables:  Hours_Studied, Age, Region. Call it *model1*. Display the summary. Using “model1”, interpret the coefficients of the following predictors below with respect to BOTH the log-odds of turnover and the odds of completed. 1) Hours_Studied 2) RegionWest (5 points)  b) Using the “trainData” dataset, create a logistic regression model using Completed as response variable and all variables in “trainData” as predictors (call it model2) and display the summary of model2. Using the model coefficients, how would you compute the predicted probability of completion for a 30-year-old male from the South enrolled in the free course who studied 10 hours and submitted 5 assignments? (10 points) c) This dataset is without replications. Aggregate the response data to convert it into binary data with replications. (Use categorical variables only)Fit the following logistic models:i) Using aggregated data. Call it model.agg. Display the summaryii) Using the non-aggregated data. Call it model.withoutagg. Display the summary. (Use the same categorical variables as in model.agg) What is the difference between the coefficients of both the models? ExplainHow are the null and residual deviance different for both models? Explain (3 points) d) Perform a test for overall regression of the logistic regression “model.agg”, using a significance level of alpha=0.05. Does the overall regression have explanatory power? Provide interpretation of the test. (3 points) e) Perform the goodness of fit test on model.agg using deviance and Pearson residuals and interpret the results. (4 points) f) Evaluate the predicting power of the “model.withoutagg” in Q2c using cross validation.

Assume a residential mortgage lender has agreed to provide a $400,000 fixed rate, level payment, fully amortizing mortgage loan to a home buyer. The (annual) contract interest rate is 6.00%. The monthly payment loan will be amortized over 30 years. Thirty days have passed since the lender committed to finance the mortgage. On the day of closing, contact interest rates on this type of mortgage have increased from 6.00% to 6.50%. Assume secondary mortgage market investors assume this type of mortgage will remain outstanding for 6 years before being prepaid by the borrower. To sell the originated loan in the secondary mortgage market on the day of closing, the originating lender will have to discount the price by:

Assume you have taken out a “balloon” mortgage loan for $2,500,000 to finance the purchase of a small commercial property. The loan has a term of 5 years, but amortizes over 25 years. Calculate the balloon payment at loan maturity if the contract interest rate on this loan is 4.5%.

Four years ago, you obtained a $4,000,000 interest-only (I-O) mortgage to help finance the acquisition of a small rental property. The original loan term is 10 years. The remaining loan term is 6 years (4 years have passed). The interest rate on the existing mortgage is 6.00% (annual). A new interest-only mortgage for $4,000,000 with a 4.75% (annual) rate can be obtained. The cost of obtaining the new mortgage will be 3% of current loan balance. A prepayment penalty equal to 2% of the remaining mortgage balance will also need to be paid to the original lender to refinance. The expected time before paying off any outstanding loan is 6 years from today. What is the net present value (NPV) of refinancing today?

In an assigned article on homeownership by Lau Vegys and Doug Casey titled “The Vanishing American Dream: Why Young Adults Can’t afford Homes, Families, or Stability,” the authors attempt to explain why the percentage of 30-year-olds that are married and own a home has declined over the last 50 years. Which of the following was not offered as a potential explanation?

Which of the following types of loans are often used to provide short-term financing for “transitional” properties (e.g., properties that are currently experiencing heightened vacancies, or that need to be redeveloped or renovated before they can be stabilized)?

If a household that owns its home chooses to take the standard deduction instead of itemizing their “personal” expenses on “Schedule A” of their federal income tax return (Form 1040), the federal tax savings associated with property tax and mortgage interest expenses
