What would the r-squared be if the sum of squares due to regression (SSR) is 883.9, and sum of squares due to error (SSE) is 406.2? Please round your answer to four decimal places.

Use the CarInsurance sheet. Develop a multiple linear regression model to predict the monthly car insurance premium based on the age of the driver and the type of car (sedan, SUV, or sports car). Use sedan as the baseline. What is the estimated monthly insurance premium for a 50-year-old driver with an SUV? Please round your answer to the nearest integer.

Use the Demand Sheet. Construct a simple linear regression that estimates Demand based on Year. What is the forecasted demand in Year 18? One decimal place.

Use the Demand Sheet. Use the exponential smoothing method with an alpha of 0.4 to predict the profit in Year 2-10. What is the mean squared error (MSE)? Two decimal places.

Use the Frequency sheet. Use a bin width of 10 to create a frequency distribution (0-10, 11-20, etc.). How many data points are between 31-40? Based on the frequency distribution you obtained, the data is skewed.

The nurse is caring for a client with chemotherapy-related nausea and administers promethazine for the first time. Which precaution should the nurse put into place for this client?  

A concentrated sodium chloride solution is supplied as a 14.6%w/v solution with a specific gravity of 1.1. What is the w/w% of the solution? Please round the final answer to one decimal place, except no trailing zeros. %w/w

CHANGE to diphenhydramine. A nurse is given an order to give promethazine 25mg IVP administered slowly over 15 minutes. They have available a 50mg/mL vial of promethazine and know that they must dilute the dose to prevent tissue damage and irritation. According to hospital policy they must dilute the promethazine to 1.25mg/mL with NS. How many milliliters (mL) of NS must the nurse add to the promethazine dose to dilute it to 1.25mg/mL? Please round the final answer to one decimal place, except no trailing zeros.    mL
