Consumer reports stated that the mean time for a chrysler concorde to go from 0 to 60 miles per hour was 8.7 seconds. (a) if you

want to set up a statistical test to challenge the claim of 8.7 seconds, what would you use for the null hypothesis? μ > 8.7 μ = 8.7 μ ≠ 8.7 μ < 8.7 (b) the town of leadville, colorado, has an elevation over 10,000 feet. suppose you wanted to test the claim that the average time to accelerate from 0 to 60 miles per hour is longer in leadville (because of less oxygen). what would you use for the alternate hypothesis? μ = 8.7 μ ≠ 8.7 μ < 8.7 μ > 8.7 (c) suppose you made an engine modification and you think the average time to accelerate from 0 to 60 miles per hour is reduced. what would you use for the alternate hypothesis? μ > 8.7 μ = 8.7 μ < 8.7 μ ≠ 8.7 (d) for each of the tests in parts (b) and (c), would the p-value area be on the left, on the right, or on both sides of the mean? both; left left; both right; left left; right

Answer:

Volume of round cake pan = volume of cylinder

Volume of a cylinder = \pi r^2h (where r is the radius and h is the height)

Radius = \dfrac12 diameter ⇒ r=\dfrac72=3.5

⇒ volume of round cake pan = \pi \times 3.5^2 \times 2=24.5\pi

= 76.97 in³ (nearest hundredth)

Volume of rectangular cake pan = volume of rectangular prism

volume of rectangular prism = wlh (where w is the width, l is the length and h is the height)

⇒ volume of rectangular cake pan = 6 x 9 x 2 = 108 in³

As 108 > 76.97, the rectangular cake pan has a larger volume
