The conclusion is incorrect due to the fact that the sample is biased
Take a random sample of 50 from a student population, such as an english class
To find the mean add up each value and divide by the number of values
Planted society- 40+20+16+20+17+12+15=140
140/7=20
Bees park- 25+12+9+15+35+20+6+30=152
152/8=19

Answer:
0.02 mm
Step-by-step explanation:
Let's convert the numbers given in decimal first, for ease of calculation.
Thickness of soles of feet = 1 2/5th mm, which is 1.4 mm
THick ness of eyelids are 1/70 TIMES the thickness of soles
So we multiply 1/70 [in decimal that is 0.0143 (rounded to 4 decimals) ] with 1.4:
0.0143 * 1.4 = 0.02 mm
So, the thickness of skin on your eyelids is 0.02 mm
