Explanation:

Step1: Calculate total number of teams

Add up the frequencies of all intervals: $6 + 11+3 + 1+12 + 14+7=54$. So option A is incorrect.

Step2: Analyze option B

The frequency of teams that made 26 - 30 field - goals is 14. Since $54\div2 = 27$, 14 is less than half of 54, so option B is incorrect.

Step3: Check option C

The frequency of teams that made 21 - 25 field - goals is 12, not 13, so option C is incorrect.

Step4: Calculate number of teams with 26 or more field - goals

Add the frequencies of the 26 - 30 and 31 - 35 intervals: $14 + 4=18$. Option D is correct.

Answer:

D. A total of 18 teams made 26 or more field goals.
