Answer:
Define observation and an inference:
An observation is something you sense: taste, touch, smell, see, or hear.
An inference is something you decide or think about a thing or event after you observe it.
The Difference
An observation is something you <u>observe</u>. Something you or others sense. While an inference is something you <u>infer</u> about someone, something, or even a situation. The <u><em>difference</em></u> is when you experiment something, you make a hypothesis, or in this case, an inference. An inference about what you think will happen (guess/theory). The next step is to observe the object or what you're focusing on. Therefore, the two are not one and the same, but very different.

Answer:
51.84%
Explanation:
p² + 2pq + q² = 1 and p + q = 1
p = frequency of the dominant allele in the population
q = frequency of the recessive allele in the population
p² = percentage of homozygous dominant individuals
q² = percentage of homozygous recessive individuals
2pq = percentage of heterozygous individuals
p = 0.72 => p² = 0.72² = 0.5184
=> Percentage of the rats are normal sized: 51.84%
