Considering the hypothesis tested and the p-value of the test, the correct option is given by:
There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.
<h3>What are the hypothesis tested?</h3>
At the null hypothesis, it is tested if there is no difference between the cholesterol levels, that is:
At the alternative hypothesis it is tested if there is a difference, hence:
The p-value is of 0.003 < 0.01, hence we reject the null hypothesis and conclude that there has was a difference, hence the correct option is given by:
There is sufficient evidence that there is a difference in mean cholesterol level when using medicine X and medicine Y.

Answer:
45°
Step-by-step explanation:
<u>Let </u><u>:</u><u>-</u><u> </u>
<u>We </u><u>know </u><u>:</u><u>-</u>
- The sum of supplementary angles is 180° .
<u>On </u><u>adding</u><u> </u><u>:</u><u>-</u><u> </u>
→ x + 3x = 180°
→ 4x = 180°
→ x = 180°/4
→ x = 45°
<h3>
Hence the smaller angle is 45° .</h3>
