Answer:
Σxi =56.61
Σxi²=196.23
Step-by-step explanation:
X be the random variable represents area of scleral lamina (mm2) from human optic nerve heads
Σxi can be obtain by adding all x values
Σxi=2.79+2.53+2.78+3.79+2.33+2.72+3.88+4.15+3.79+4.43+3.47+4.47+2.5+3.61+2.77+3.53+3.07=56.61
Σxi =56.61
Σxi² can be obtained by squaring x values and then adding them.
Σxi²=2.79²+2.53²+2.78²+3.79²+2.33²+2.72²+3.88²+4.15²+3.79²+4.43²+3.47²+4.47²+2.5²+3.61²+2.77²+3.53²+3.07²=196.233
Σxi²=196.23
