Let us suppose that yhat=12+34x with R2=90% is the regression equation for predicting the number of chocolate chips in a tub of chocolate chip ice-cream based on the amount of ice-cream in the tub (measured in pints). Use this information to answer the Chocolate Chip Ice-Cream questions that follow. Flag question: Question 12 Question 120 pts Chocolate Chip Ice-Cream Which of the following is a correct interpretation of the slope? Group of answer choices The amount of ice-cream is expected to go up by 34 pints when the number of chocolate chips goes up by 1. The number of chocolate chips is predicted to go down by 34 when the amount of ice-cream goes up by 1 pint. We might expect to see 34 additional chocolate chips for every additional pint of ice-cream. The number of chocolate chips is predicted to go up by 34 when the amount of ice-cream goes up by 12 pints. Flag question: Question 13 Question 130 pts Chocolate Chip Ice-Cream Which of the following is a correct interpretation of the y-intercept? Group of answer choices An empty tub of ice-cream is predicted to have 12 chocolate chips. The number of chips is predicted to be 34 when the amount of ice-cream is zero pints. The number of chips is predicted to be 12 when the amount of ice-cream is 1 pint. A 12-pint tub of ice-cream is predicted to have no chocolate chips. Flag question: Question 14 Question 140 pts Chocolate Chip Ice-Cream What is the linear correlation coefficient for number of chips and amount of ice-cream? Group of answer choices 0.810 0.300 0.900 0.949 Flag question: Question 15 Question 150 pts Chocolate Chip Ice-Cream Since R2 is 90%, we will assume that the model is fairly well-fitting. In this case, what would be the predicted number of chocolate chips in a 7.5-pint tub of ice-cream? Assume that 7.5 is within the range of observed data. Group of answer choices 267 124 243 345

Homework assignment 1 Write a program in MATLAB that performs the following task: Shows a text-based menu which looks exactly as shown in the figure below: Unit conversion utility Choose what conversion you want to perform: Meters to miles Miles to meters Watts to horsepowers Horsepowers to Watts Kilograms to pound-mass Pound-mass to kilogram Insert a choice [1-6]: Waits for the user to enter a number between 1 and 6 to choose one of the avalable options. If choice made by the user is not a number between 1 and 6 , the program must exit, suggesting to try again (by restarting the program) shown below: Insert a choice [1-6]: อ Invalid choice. Please, try again. Then a ralid choice is made by the user, asks the user to insert a value to be converted according to the choice made. For example, if the user has chosen option 2 , the program should show: Insert the quantity in mi to be converted into m : After the user has inserted a ralue and pressed Enter, performs the conversion and show the results, formatted exactly as shown below: Insert the quantity in mi to be converted into m : 12 12mi is equal to 19312.128m Requirements Use a custom function to format the message and read the input value to be converted from the user.
