Find the mean and standard deviation of the sampling distribution, Statistics Assignment Homework Help
1.
A farmer divided a field into 1-foot by
1-foot sections and tested soil samples from 32 randomly selected sections in
the field. He finds that the mean pH level of the samples is 5.7 with a
standard deviation of 0.26.
(a) Find
the mean and standard deviation of the sampling distribution of all possible
soil samples of size . Round to three decimal places.
(b) Construct
a 95% confidence interval for the mean pH level of soil samples from every
1-foot by 1-foot section. Show your work. Even if you use technology, show the
expression that is used to determine the margin of error for the interval.
Interpret the interval in a complete sentence.
(c) The
farmer tested soil samples from 34 randomly selected sections from another
field. He found the mean pH level of those samples to be 6.1 with a standard
deviation of 0.34. Construct a 95% confidence interval for the difference
between the mean pH levels of all possible soil samples from both fields. Show
your work. Even if you use technology, show the expression that is used to
determine the margin of error for the interval. Interpret the interval in a
complete sentence.

CSU Mod 2 Coefficient of Variation & Standard Deviation Research
The coefficient of variation and the standard deviation are two measures of variability or dispersion among data values. Provide two different sets of ten data points each as examples. Calculate the standard deviation and coefficient of variation for each data set, being sure to attach your Excel file to show your work. Explain which of the two mentioned measures can more accurately specify which of these two data sets has more variability or dispersion in their data values and why.Research the method behind the Excel function βQUARTILE.EXCβ for calculating quartiles for a given data set. Summarize this method in your own words and discuss how it differs from the method presented in the textbook and lecture.Your document should be minimum 400 words. Please have credible references.

Los Angeles Pierce College Choose a Variable Statistical Analysis Question
Choose any variable you want to measure (e.g., cups of coffee consumed per week, minutes of screen time per day, etc.) and collect data from a sample of your choice (e.g., children, adults, college students, family members, etc.) of minimum size n=10. Complete the following:
What specific variable are you measuring and what is your sample of interest?
Is your variable continuous or discrete?
Which scale of measurement is your variable categorized as (nominal, ordinal, interval, or ratio)?
Calculate the mean, median, and mode for your sample.
Draw a scatterplot or a histogram (whichever is appropriate for your data). You can use a computer program to create this graph, or simply hand-draw it and include a picture (e.g., taken with your phone) within your document.
