在Python中,当你执行一个统计测试,如上述的单样本T检验,得到的`alternative hypothesis: true difference in means is not equal to 0`意味着你在检验原假设(平均值差异为零),而备择假设(alternative hypothesis)认为这两个群体的均值之间存在差异。`95 percent confidence interval: -0.6861272 18.9956510`表示在95%的置信水平下,控制组和臭氧组的均值之差的范围大约是从-0.686到18.996。
如果你想在Python中显示这些信息,你可以这样做:
```python
confidence_interval = (-0.6861272, 18.9956510)
print(f"95% Confidence Interval for the difference in means: ({confidence_interval[0]:.3f}, {confidence_interval[1]:.3f})")
```
这会打印出类似这样的输出:
```
95% Confidence Interval for the difference in means: (-0.686, 18.996)
```
其中`.3f`指定浮点数的小数位数为3位。
