Research Question: Is there a difference in heights between steel skyscrapers and concrete skyscrapers? The statistical hypotheses are as follows: Run the correct t-Test. What is the correct conclusion?
1) The p-value is extremely small, smaller than any reasonable alpha, so we conclude that there is NOT a difference in average heights.
2) The p-value is extremely small, smaller than any reasonable alpha, so we conclude that there is a difference in average heights.
3) The p-value is extremely large, larger than any reasonable alpha, so we conclude that there is a difference in average heights.
4) The p-value is extremely large, larger than any reasonable alpha, so we conclude that there is NOT a difference in average heights.
