Laura is a human resources director for a manufacturing plant. She has become concerned with the number of safety violations that have been reported by supervisors. She decides to start a safety seminar that all employees will need to attend. Using her computer, she creates a spreadsheet that will track the number of violations over the next six months as all employees attend the seminar. The x-axis will represent the number of employees who have completed the seminar and the y-axis will represent the number of safety violations reported. The spreadsheet will automatically create a scatterplot with a line of best fit. What does she hope to see as she implements her plan? O a positive correlation, indicating safety improvement O a negative correlation, indicating safety improvement O no correlation, indicating safety improvement O a curving line that starts out as a positive correlation and turns negative to indicate safety improvement
I'm looking at the coefficents between two variables on Excel. Copying and pasting is not recommended by my professor. Can anyone give me an idea on how to graph it?
Degrees Earned The number of postsecondarydegrees earned, in thousands (including associate’s,bachelor’s, master’s, first professional, and doctoral degrees), can be modeled by y = 3.980x2 -17.597x + 2180.899, where x is the number of yearsafter 1990. If this model is accurate, during what yearsfrom 1990 on would the number of postsecondarydegrees earned be less than 3500 thousand?
Explain what is meant when two variables are positively linesrly related. What would scatter plott look like? Two variables x and y are postively linearly related if when the x value increases , the y value increases or decrease? The points on a scatter plot fall approximately in a-an ascending straight line b- a descending curve c- a descending straight line or d- an ascending curve from left to right?
