The weights of 19 hummingbirds are given below in ounces. \( 11,8,10,10,10,9,4,9,7,5,11,8,9,11,10,10,10,9,10 \) Find the mean weight of the hummingbirds. (It will be a decimal)

Calculate or simplify the expression \( \frac{11+8+10+10+10+9+4+9+7+5+11+8+9+11+10+10+10+9+10}{19} \). Calculate the value by following steps: - step0: Calculate: \(\frac{11+8+10+10+10+9+4+9+7+5+11+8+9+11+10+10+10+9+10}{19}\) - step1: Write as a multiplication: \(\frac{11\times 3+8+10\times 7+9\times 4+4+7+5+8}{19}\) - step2: Multiply the numbers: \(\frac{33+8+10\times 7+9\times 4+4+7+5+8}{19}\) - step3: Multiply the numbers: \(\frac{33+8+70+9\times 4+4+7+5+8}{19}\) - step4: Multiply the numbers: \(\frac{33+8+70+36+4+7+5+8}{19}\) - step5: Add the numbers: \(\frac{171}{19}\) - step6: Reduce the numbers: \(\frac{9}{1}\) - step7: Calculate: \(9\) El peso medio de los colibríes es de 9 onzas.
