In a survey of 3228 randomly selected U.S. adults, 41% reported that they have at least one chronic health condition, such as diabetes or high blood pressure. Among those surveyed, 1455 were called by landline and 1773 were called by cell phone. What percentage of the survey subjects were called my cell phone?

To find the percentage of survey subjects who were called by cell phone, use the formula:

\[
\text{Percentage of cell phone calls} = \left( \frac{\text{Number of cell phone calls}}{\text{Total number of survey subjects}} \right) \times 100
\]

In this case, the number of survey subjects called by cell phone is 1773, and the total number of survey subjects is 3228. Substituting the values:

\[
\text{Percentage of cell phone calls} = \left( \frac{1773}{3228} \right) \times 100
\]

Let's calculate this.

\[
\text{Percentage of cell phone calls} = \left( 0.5494 \right) \times 100 = 54.94\%
\]

So, approximately **54.94%** of the survey subjects were called by cell phone.
