Statistical analysis and presentation of results from a complex data set about ladybirds.

You are given a complex data set on the variation of ladybirds

This data can be used to examine a range of possible hypotheses.

Your task is to state produce a succinct report on this data.

Your report should have the following sections.

Keep each section to a different page(s) and provide a heading to each page as follows.

A.
A statement of which TWO scientific hypothesis or hypotheses that you want to examine. Of course, normally in a scientific investigation you would state the hypothesis before collecting the data!
Heading - "Scientific hypotheses"

B.
Relevant tables of summary statistics:
Heading "Tables and summary statistics"

C.
Relevant exploratory figures and graphs:
Heading "Exploratory figures and graphs"

Scientific hypotheses
First Hypothesis:
Null Hypothesis (Ho): There is no significant difference in Dry Weight (mg) with respect to Species. In other words, there is no significant difference in Dry Weight (mg) between Adalia bipunctata and Adalia decempunctata.
Alternative Hypothesis (Ha): There is a significant difference in Dry Weight (mg) with respect to Species. In other words, there is a significant difference in Dry Weight (mg) between Adalia bipunctata and Adalia decempunctata.
Mathematically;
Null Hypothesis (Ho): µ1 = µ2
Alternative Hypothesis (Ha): µ1 ≠ µ2
Where µ1 is the population mean of Dry Weight for Adalia bipunctata and µ2 the population mean of Dry Weight for Adalia decempunctata.

Second Hypothesis:
Null Hypothesis ...
