Explanation & Answer
This is a classic SAT work problem. The first part of the problem gives us a rate: 6 workers can build a barn in 4 days. Then, they mix things up. Now we have 12 workers buildi...

Please properly cite the work. Use the internet to find one example of each of the following graphs:Line graphBar graph (horizontal or vertical bars are acceptable)Pie graphSuppose you were presenting these graphs to a group of people (clients, co-workers, friends, etc.) who are not mathematically savvy.Create a 7- to 10-slide presentation with speaker notes that provides a non-technical explanation of each graph. Remember, you are addressing people who probably do not like or understand mathematical terms. For each graph, include the following:Screenshot of your graph.For the line graph, what are the labels on the horizontal and vertical axes? For the bar graph, what labels are on the bars? What is being measured in this graph? (Hint: look at the axis label.)For the pie graph, what is the title, in other words, what is it measuring?How would you improve each graph if at all? Is anything missing, misleading, or perhaps just wrong with this graph?What would be the appropriate measure(s) for central tendency (mean, median, mode) to display with each graph?What measure of dispersion (range, standard deviation) would be best?Provide a reference citation for the source of your graph so your facilitator can find the graph online.

Moore College of Art and Design Hypothesis Test for a Population Mean Discussion
Learn by DoingThis activity gives you practice explaining the different parts of
the StatCrunch print-out for a hypothesis test for a population mean.
You will review the meaning of standard error, T-scores and the P-value.Some features of this activity may not work well on a cell phone or
tablet. We highly recommend that you complete this activity on a
computer.Here are the directions, grading rubric, and definition of high-quality feedback for the discussion board exercises. A list of StatCrunch directions is provided at the bottom of this page.PromptIn a previous lab we tested the following hypotheses,

μ

and

(where
μ
is the mean number of alcoholic drinks consumed by students at a liberal arts college).In
a random sample of 75 students, the mean was 3.93 alcoholic drinks
consumed in a week. Here is the StatCrunch output from the hypothesis
test.
