 Hello and welcome to this session. In this session, we will discuss a question which says that the number of working hours and the wages in dollars of 10 employees are given below. Job is cut a plot and line of best fit on the graph in calculator. Now let us start with the solution of the given question. In this question, we are given a table showing number of working hours of 10 employees and their wages in dollars. We have to draw the scatter plot and the line of fit for the given data using graph in calculator. Let the working hours represent x values and wages represent y values. First press start and we get the following display. Now press number 1 to select edit from the menu and we get the following display. The start list editor is displayed. L1 and L2 columns are given. We will store our data in L1 and L2. In L1 enter all the x values from the given data. For this, write the value 8 and press enter then write 11 and press enter and so on. And we have the following display. Now scroll to write in L2 column and write all the y values given in the data in the similar way. And we get the following display of values on screen. Now press second and we write y is equal to key to get the display of start plot on screen. And we get the following display. Now press number 1 key to select plot 1. Start plot editor is displayed on screen. Press enter to select on which turns on plot 1. Scroll down press enter to select type of display. We want scatter plot so we move cursor to image of scatter plot and press enter. Now again scroll down and press second. Followed by number 1 key because L1 is written above number 1 key to specify x list L1 for plot 1. Similarly press second followed by number 2 key to specify y list L2 for plot 1. Now scroll down to select the mark for data points dot plus sign or square. We select plus as the mark for each data point by scrolling to plus sign and pressing enter key. Now press zoom and we get the following display. Scroll down and now press line number key to select zoom stat from the zoom value. The window variables are adjusted automatically and plot 1 is displayed. And this is the scatter plot of the given data. Now let us fit a line to the data. For this press stat then scroll to the right stat can see menu is displayed. Press 4 number key to select regression line AX plus B. We get the following display on screen. Now press second L1 followed by comma key and second L2 followed by comma key. C L1 and L2 are now displayed along with the regression line. Now press where key that is variable key and we get the following menu on screen. Scroll to right where function is displayed. Select function by pressing number 1 key and we get this display. Now select y1 by pressing number 1 key. So we get L1, L2 and y1 displayed on screen. Now press enter key to execute linear regression AX plus B. And we get the following display. The linear regression for the data in L1 and L2 is calculated. Values for A and B are displayed in the home screen. The linear regression equation is stored in y1. Now press graph. The regression line and scatterplot are displayed. And now press press to get the display of the coordinates and points in data set. And this is the required line of fit. So for the given data we have drawn the scatterplot and the line of best fit on the graph calculator. And this is the solution of the given question. That's all for this session. Hope you all have enjoyed the session.
