A recent debate about where in the United States skiers believe the skiing is best prompted the following survey. Test to see if the best ski area is independent of the level of the skier. (Use a significance level of 0.05.)U.S. Ski AreaBeginnerIntermediateAdvancedTahoe222940Utah113260Colorado113850

• Part (a)
• State the null hypothesis. Multiple Choice

a) Ski area is independent of the level of the skier.

b) Ski area is dependent on the level of the skier.

• Part (b) (Multiple Choice)
• State the alternative hypothesis.

a) Ski area is independent of the level of the skier.

b) Ski area is dependent on the level of the skier.

• Part (c)
• What are the degrees of freedom? (Enter an exact number as an integer, fraction, or decimal.)
• _________
• Part (d) Multiple Choice
• State the distribution to use for the test.

a) 24

b) t₄

c) t₂

d) 22

• Part (e)
• What is the test statistic? (Round your answer to two decimal places.)
• ________
• Part (f)
• What is thep-value? (Round your answer to four decimal places.)

P=_________

• Explain what thep-value means for this problem. Multiple Choice

a) IfH₀is true, then there is a chance equal to thep-value that the value of the test statistic will be equal to or greater than the calculated value.

b) IfH₀is false, then there is a chance equal to thep-value that the value of the test statistic will be equal to or less than the calculated value.

c) IfH₀is false, then there is a chance equal to thep-value that the value of the test statistic will be equal to or greater than the calculated value.

d) IfH₀is true, then there is a chance equal to thep-value that the value of the test statistic will be equal to or less than the calculated value.

• Part (g)
• Sketch a picture of this situation. Label and scale the horizontal axis, and shade the region(s) corresponding to thep-value.
• Part h

Indicate the correct decision ("reject" or "do not reject" the null hypothesis) and write the appropriate conclusion.

(i) Alpha:

=_____

(ii) Decision:

a) reject the null hypothesis

b) do not reject the null hypothesis

(iii) Reason for decision:

a) Since<p-value, we do not reject the null hypothesis.

b) Since>p-value, we reject the null hypothesis.

c) Since>p-value, we do not reject the null hypothesis.

d) Since<p-value, we reject the null hypothesis.

(iv) Conclusion:

a) The best ski area and level of skier are not independent.

b) The best ski area and level of skier are independent.
