Caffeine in a sample of chocolate was measured five times, and the results were 1265 ppm caffeine with a standard deviation of 9 ppm. According to the product label, the chocolate contains 1250 ppm caffeine. Are the experimental results statistically different from the label value at the 95% confidence level? a. Yes, because tcalc < ttable
b. Yes, because tcalc > ttable
c. No, because tcalc < ttable
d. No, because tcalc > ttable

11 players on a field that has a maximum of 11 players

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."

the answer would be c

c.
