Answer: t= -1.60
Explanation:
Let 
be the population mean weight of pigs.
As per given , we have
Sample size : n= 16
Sample mean =
Sample standard deviation : 
<em>Since the population standard deviation is not known so the test is a</em><em> t-test.</em>
Test statistic for population mean : 
(Substitute all the values.)
Hence, the value of the test statistic needed to test the null hypothesis : t= -1.60
I'm not entirely sure why holistic treatments would be controversial in
animals. Perhaps what makes them controversial is the fact that we tend
to assume we know what makes them holistic and how they will be holistic
for the animal - this isn't necessarily the case, as we can only make a
good guess about it.
Answer:
Natural selection is when an animal adapts to their environment to survive and produces more offspring. It occurs when the animal isn’t thriving in their environment and they make adaptions to where they can survive.
Explanation:
An example of natural selection is, a bird used to have a really thick and short beak. But to have more access to food they adapted to their environment and now have a long and skinny beak.
Hope this helps :)
