how would i test my hypothesis that larger galls have more insects that emerge from them in this research study project, I have included the data, gall id is just the identifier for each gall, gall volume is the size, we used volume that was calculated from the diameter because its more accurate on gall size, and number of insects represents the number of insect holes counted on old galls. additionally the new galls we collected did not produce sufficient data and were omitted from our study. i calculated the correlation coefficient to be 0.531418 which means we have a moderately positive correlation. now how do I apply this to test hypothesis and obtain a p- value.

I've been trying for 10 hours to figure this out now and I'm getting fucking frustrated!!!! excuse my language. thank you
Transcribed Image Text:6. Resource quantity and productivity in gall-inducing wasps. Valley Oaks (Quercus lobata) support
an array of galling wasps of the family Cynipidae. One of the best-known of these is the California Gall
"Fly," Andricus quercuscalifornicus, which is the species responsible for the conspicuous Oak "Apples"
(actually plant galls). Despite the size of these galls, some of which can reach the size of a baseball, the
wasps are only about 5 mm long and are seldom seen. A single gall may harbor multiple larvae of the
wasp, together with a community of inquilines (uninvited "guests") and parasitoids (other wasps which
consume the gall-inducers themselves). It is possible to estimate the number of gall wasps emerging from
the galls, as well their associates, and plot this as a function of gall size. Therefore, the greater the
quantity of resources (i.e., the larger the gall), the more productive the gall (from the perspective of the
insects).
Procedure: Collect active oak galls from branches of Valley Oaks (Bidwell Park is a good place to do
this). You may recognize active galls by their bright color, which ranges from a pale greenish-tan to a red,
not unlike a true apple. Place these in individually sealed zip-lock bags and store them in the lab,
checking on them regularly for any emerging insects over a period of four weeks. Save the insects in
ethanol and try to distinguish as many species as possible, noting how many have emerged from each gall
and whether they are A. quercuscalifornicus or perhaps their parasitoids or inquilines. Watch carefully for
any mold and transfer galls to fresh bags if necessary. As a backup data set, collect and bag 50 older galls
as well (these are usually soot-colored). Measure the maximum gall diameter with calipers, as well as the
inside diameter of any exit holes already present on the old galls and after four weeks on the new galls.
You should be able to test for significance on the number of insects produced as a function of gall size.

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
