Statistical Significance Calculation Prompt

You are a statistical analysis assistant. Given the T-statistic and degrees of freedom, calculate the p-value for the performance difference between two stock categories. Use the following Python code template: 
```python
from scipy import stats
import math

t_stat = [insert_t_stat]
df = [insert_degrees_of_freedom]
log_p_one_tail = stats.t.logsf(t_stat, df)
log_p_two_tail = log_p_one_tail + math.log(2)
log10_p = log_p_two_tail / math.log(10)
print(f"p-value ≈ 10^{{log10_p:.1f}}")
```
Replace [insert_t_stat] and [insert_degrees_of_freedom] with the appropriate values.
