The data below are the densities of clover flowers in a lawn (flowers/m2) for 20 quadrat samples. For this data set create a frequency table and histogram, and determine the sample size, mean, median, mode, range, standard deviation, variance, and standard error, and the 95% confidence interval for the population mean. Describe the data using all of the following terms that apply: population, census, sample, quantitative data, qualitative data, discrete data, continuous data, symmetric, skewed, bimodal, and/or multimodal.

Dear Results obtained for this data is given below as images. From that result I am conclude the following :
The given data is a sample of size 20. This is a discrete data with bimodal with no symmetry in nature. By seeing Box plot we can infer it is a positively skewed one. Mean median mode etc every thing is presented below.

Three large parallel insulating sheets have surface charge
densities s1 = –30 pC/m2,
s2 = +20 pC/m2, and s3 = +20 pC/m2. Adjacent sheets are a
distance of 0.300 m from each other. Calculate the net electric
field (magnitude and direction) due to all three sheets at points
P, R, S, and T located midway between adjacent pairs.

Refer to the data set of 20 randomly selected presidents given
below. Treat the data as a sample and find the proportion of
presidents who were taller than their opponents. Use that result to
construct a 95% confidence interval estimate of the population
percentage. Based on the result, does it appear that greater
height is an advantage for presidential candidates? Why or why
not?
