Yes its following normal assumption, but very weakly, the QQplot
must have a 45 degree line connecting the points.
Correct hypothesis is H0 :
1 = 2
=
3
and correct laternative hypothesis is Ha :
ij
, for some ij
Correct answer is the distribution for F-test statistic which is
the F-distribtion
Notation:
A: Toads
B: Forgs
C: Salamanders
therefore p<0.005 is the range where p=0.0006 lies. option 1 is
the correct answer.

Samples of three different species of amphibian (frog, toad and salamander) were collected and dissected and the number of parasites found within each was counted and recorded. The researchers are interested in determining whether the distribution of parasites across species is different. The number of parasites within each sample was counted and recorded.

A group of researchers on Sable Island are wondering whether the grey seals pups on the west side of the island grow at different rates than those on the east side of the island. To test this they measured the weight of 20 one week old grey seal pups on the west side of the island and 22 one week old grey pups on the east side of the island. They found that the average weight of one week old...

A group of researchers on Sable Island are wondering whether the grey seals pups on the west side of the island grow at different rates than those on the east side of the island. To test this they measured the weight of 27 one week old grey seal pups on the west side of the island and 20 one week old grey pups on the east side of the island. They found that the average weight of one week old...
[5 total pt(s)] Grey seals are capital breeders and stay with their pups until they are weaned. A group of researchers on Sable Island are interested in seeing whether there is a significant difference in the weight of one week old grey seal pups versus two week old pups. They measured the weight of 21 one week old pups, then weighed those same pups again one week later. The researchers found the average weight of adult female grey seals was...
