Consider the scatter plot and trend line to the right. Should the trend line for the temperature be expected to continue in the same direction indefinitely? Explain. 100- 90- 80- 70- 50- 40- 1234 5 67 Time (hours) O A. No. It should not be expected to continue in the same direction indefinitely. Trend lines cannot be used to make inferences beyond the data used to make it. O B. No. It should not be expected to continue in the same direction indefinitely. The outdoor temperature should be expected to increase more and more quickly over time. This means if more data were collected, the pattern in the scatter plot would start to curve up. O C. Yes. It should be expected to continue in the same direction indefinitely. The trend line models the given data well, so it can be expected to also model the situation well as x increases indefinitely. O D. Yes. It should be expected to continue in the same direction indefinitely. The data have a clear association, so the trend line should…
