Answer:
How to calculate the mean of a data set:
Sum of all the numbers in the data set / the no. of "ValuEs" in the data set
Therefore, we can solve and conclude that:
1) = 29+42+45+39+36+41+38+37+43+35+32+40 / 12
= 457 / 12
= 38.083 (38 to the nearest whole number)
___________________________________________________
2) = 19.90+24.45+34.65+26.50+44.05+38.95+56.40+48.75+29.30+35.65 / 10
= 35.86 (36 to the nearest whole number)
Hope I helped ^^
