\boxed{\text{Mean: 27.7, Median: 26.0, Mode: None}}

Steps

Step 1 :Find the mean: \(\frac{21+33+27+20+36+34+25+22+29+30}{10} = 27.7\)

Step 2 :Find the median: Sort the numbers and find the middle value: \(\frac{25+27}{2} = 26.0\)

Step 3 :Find the mode: Since all numbers appear only once, there is no mode.
