Question

Suppose that your test statistic is t(99 ) = -2.8888. Round the test statistic to two places after the decimal point.

Answer 1

Answer:

t(99)= -2.89

Step-by-step explanation:

-To places after the decimal point is equivalent to rounding off to the nearest hundredth.

-To round off to the nearest hundredth, we check the thousandths digit:

• If the thousandths digit is less than5, we round down to the previous hundredth.
• If the thousandths digit is greater than 4, we round up to the next hundredth:

Hence,$-2.8888\approx-2.89$
