Question

the newspaper reported that on the "big board," where 1.24 billion shares were traded, 1,366 stocks fell and 1,788 rose. On the NASDAQ, where 1.76 billion shares were traded, 1,587 fell and 2,068 rose. Comparing the fractions of stocks that fell to the stocks that rose, which market had the largest fraction?

Answer 1

Using proportions, it is found that the Big Board market had the largest fraction.

------------------------

Big board:

• Total of 1366 + 1788 = 3154 stocks.
• Of those, 1788 rose.

The proportion that rose is:

$p_B = \frac{1788}{3154} = 0.5669$

------------------------

NASDAQ:

• Total of 1587 + 2068 = 3655 stocks.
• Of those, 2068 rose.

The proportion that rose is:

$p_N = \frac{2068}{3655} = 0.5658$

$p_B > p_N$, thus, the Big Board market had the largest fraction.
