In an effort to link cold environments with hypertension in humans, a preliminary experiment
was conducted to investigate the effect of cold on hypertension in rats. Two random samples
of 6 rats each were exposed to different environments. One sample of rats was held in a normal
environment at 26°C. The other sample was held in a cold 5°C environment. Blood pressures and
heart rates were measured for rats for both groups. The blood pressures for the 12 rats are shown
in the accompanying table.
a. Do the data provide sufficient evidence that rats exposed to a 5°C environment have a
higher mean blood pressure than rats exposed to a 26°C environment? Use a  .05.
b. Evaluate the three conditions required for the test used in part (a).

The table presents the blood pressure readings of rats at two different environmental temperatures: 26°C and 5°C.

**At 26°C:**
- Rat 1: 152 mmHg
- Rat 2: 157 mmHg
- Rat 3: 179 mmHg
- Rat 4: 182 mmHg
- Rat 5: 176 mmHg
- Rat 6: 149 mmHg

**At 5°C:**
- Rat 7: 384 mmHg
- Rat 8: 369 mmHg
- Rat 9: 354 mmHg
- Rat 10: 375 mmHg
- Rat 11: 366 mmHg
- Rat 12: 423 mmHg

**Analysis:**
- The blood pressure of rats at 5°C is significantly higher compared to that at 26°C. This indicates a potential physiological response to the colder environment.
- Blood pressure readings at 26°C range from 149 to 182 mmHg, while at 5°C, they range from 354 to 423 mmHg, highlighting a notable increase in colder conditions. This could be due to various factors such as vasoconstriction or increased metabolic demands.
