2. Ten thousand marbles were produced on a production line. The first 100 marbles off the line were taken and tested for roundness. Does this sampling
result in a simple random sample?
No, because each item does not have an equal chance of being selected.
O
Yes, because each group of n items has an equal chance of being selected.
No, because each group of n Items does not have an equal chance of being selected.
Yes, because each item has an equal chance of being selected.

< coa = 150 ( given)

as ba and bc are tangents

so oc and oa is perpendicular to cb and ab respectively because in circle normal passes through centre

so in quadrilateral oabc

< coa + < oab + < ocb + < abc = 360

150 +90+90 + < abc = 360

330 + < abc = 360

< abc = 360 -330 = 30

so < abc = 30
