Answer:
D. Both distributions are skewed left, so the interquartile range is the best measure to compare variability.
Step-by-step explanation:
Plotting the data roughly shows that the data is skewed to the left. In other words, data is skewed negatively and that the long tail will be on the negative side of the peak.
In such a scenario, interquartile range is normally the best measure to compare variations of data.
Therefore, the last option is the best for the data provided.

Answer:
Yes. Fertilization increases grape yields by more than 5 pounds.
Step-by-step explanation:
Let f-fertilized and o-old(unfertilized)
#First, we use our data to calculate the standard error:
#State both null and alternative hypothesis:
#We determine our degrees of freedom as 87.02(using R), we now compute the t-value as:
Since, the p-value is low, we Reject the null hypothesis. The is enough evidence suggesting that grape yields increase by more than 5 pounds than mean yields of unfertilized grapes.
Answer:
nucleus is a small structure located inside the cells of eukaryotic organisms. The cell nucleus is actually one of the defining characteristics of eukaryotes, as the structure allows cells and organisms to reach a very high level of complexity.
protons in the atomic nucleus is what determines the atomic number of an element, as outlined in the periodic table of the elements.Protons and neutrons, each with masses of approximately one atomic mass unit, are collectively referred to as "nucleons".
the neutron is a subatomic particle an uncharged elementary particle that has a mass nearly equal to that of the proton and is present in all known atomic nuclei except the hydrogen nucleus.
The electron is a subatomic particle, with a negative elementary electric charge.Electrons in atoms exist in spherical shells of various radii, representing energy levels. The larger the spherical shell, the higher the energy contained in the electron.
