Suppose that your psychology professor, Dr. I. D. Ego, wants to evaluate people's driving ability after 24 hours of sleep deprivation. She develops a test of driving skill (scores ranging from 1=bad driving to 10 = excellent driving) and administers it to 101 drivers who have been paid to stay awake for 24 hours. The scores from the group had a mean of 4.5 and a standard deviation of 1.6. Determine if the sleep-deprived group mean is significantly different from the known population mean of 5.8 for the driving test. Assume alpha = 0.05.

i would need to see the dot plot : )

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

hope i !
