The following is a frequency polygon of monthly exchange rate changes in the US dollar/Japanese yen spot exchange rate from January 2010 to December 2013. A positive change represents yen appreciation (the yen buys more dollars), and a negative change represents yen depreciation (the yen buys fewer dollars)

Based on the chart, yen appreciation:

选项:

A.

occurred more than 50% of the time.

B.

was less frequent than yen depreciation.

C.

in the 0.0 to 2.0 interval occurred 20% of the time.

解释:

A is correct.

Twenty observations lie in the interval "0.0 to 2.0," and six observations lie in the 2.0 to 4.0 interval. Together, they represent 26/48, or 54.17% of all observations, which is more than 50%.
