Concept explainers
(a)
To determine: The table, which shows the number of households who use online banking and the number of households who use mobile banking for the provided years.
The mathematical models for the data are,
Number of households who use online banking is
(b)
To determine: The conclusion from the comparison of the values obtained from the mathematical model and the actual data.
(c)
To determine: The model, which is obtained from the ratio of the number of households who use mobile banking and the number of households who use online banking.
(d)

- College students are graduating with the highest debt burden in history. The bar graph shows the mean, or average, student-loan debt in the United States for five selected graduating years from 2001 through 2013. Here are two mathematical models for the data shown by the graph. In each formula, D represents mean student-loan debt, in dollars, x years after 2000. The Model 1 is, D = 1188x + 16,218 and the Model 2 is D = 46x2 + 541x + 17,650. Solve, a. Which model better describes the data for 2001?b. Does the polynomial model of degree 2 underestimate or overestimate the mean student-loan debt for 2013? By how much?arrow_forwardYou’ve been wondering about the latest rise in taxi services, such as Uber and Lyft. You wondered if college students have a preference. You ask 67 college students which service they prefer. You find that 28 indicate Uber, while 39 indicate Lyft.The chi-square value is (round to 2 decimals):arrow_forwardFind the arithmetic mean of the set of data: 6, 1, 5, 8, and 10.arrow_forward

Why 1970? Because t (the number in the left column) is number of years after 1960. A pair like (10, 7.61) is called a data-point. Because it shows some data (information), and geometrically it is a point (it has two numbers). A row in our table gives us a data-point. S1. Plot the data = create a scattergram.S2. Show the graph of a line that comes close to the points in your scattegram.The line might also be known as Best fit line, Regression Line, or Least-squares regression line.S3.
