A biologist was interested in determining whether sunflower seedlings treated with an extract from Vinca minor roots resulted in a different average height of sunflower seedlings than the standard height of 15.7 cm at a 0.05 level of significance. The biologist treated a random sample of n = 33 seedlings with the extract and subsequently obtained the following heights:

A gardener plants 300 sunflower seeds (of a brand called
KwikGrow) and, after 2 weeks, measures the seedlings’ heights (in
mm). These heights are recorded in the file Sunflower.csv. He is
interested in testing whether the mean height of sunflowers grown
from KwikGrow seeds is greater than 33 mm two weeks after planting.
He decides to conduct a hypothesis test by assuming that the
sampling distribution of the sample mean has a normal distribution.

We want to compare the
soil water content (% water by volume) of two fields growing bell
peppers.
The claim is that the two fields have different soil water
content.
Use the data below to test the hypothesis that the fields have
different soil water content.
Field 1 is in list1 and Field 2 is in list2.
We do not know whether the water content values are normally
distributed or not, but their variances are equal.
Provide your answers below....
