A resesrcher asks participants to estimate the height ( in inches) of a statue that is in a waiting area. The researcher records the following estimates: 40, 46, 30, 50, and 34. If the reaearcher removes the estimate of 40 ( say due to an experimneter error), then the value of the mean will

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

i think it might be a but you might want a second opinion

something over 10 so ? /10
