A certain journal published a study on university students. Each student was assigned a task that involved determining the type of aircraft. Half of the students used a computer mouse to click on an asterisk, while the other half were given pattern-based instructions. The researcher also classified the heuristic strategy used by each student as TTBC, Guess, or Other. Data on the two variables, instruction type and strategy, were measured for each of the 48 subjects and are provided in the table. Do the data provide sufficient evidence (at 0.10) to indicate that the choice of heuristic strategy depends on the type of instruction provided? At 0.017, click the icon to view the data. X Data
Specify the null and alternative hypotheses. Choose the correct answer below.
A. Ha: The classifications TTBC, Guess, and Other are independent. Ha: The classifications TTBC, Guess, and Other are dependent.
B. Ha: The classifications Instruction and Strategy are independent. Ha: The classifications Instruction and Strategy are dependent.
C. Ha: The classifications Pattern and Cue are independent. Ha: The classifications Pattern and Cue are dependent.
D. Ha: The classifications Instruction and Strategy are dependent. Ha: The classifications Instruction and Strategy are independent.

State the conclusion for α = 0.10.
Ha: There is sufficient evidence to indicate that the two classifications are dependent at α = 0.10.
State the conclusion for α = 0.01.
Ha: There is sufficient evidence to indicate that the two classifications are dependent at α = 0.01.
