Come up with a real-life situation in which you might be curious to know if there is a difference between two means (averages). State the null and alternative hypothesis of your real-life situation.

STAT 280-Week 7 RESPOND Come up with a real-life situation in which you might be curious to know if there is a difference between two means (averages). State the null and alternative hypothesis of your real-life situation. Alternatively, you may research other examples of situations where hypothesis testing could be used in decision-making. Describe the […]

What are the main topics investigated in ancient Greek number theory? How much of number theory has a practical application nowadays?

Greek mathematics Given that we have no documents from the time of Greek mathematics—the earliest manuscripts we have are medieval—how can we be sure that the texts we have are actually what the authors wrote?Were the copyists who wrote the early medieval manuscripts simply concerned with reproducing the text faithfully, or is it possible that […]

Compare the mean vs. the median and discuss what this says about the shape of the variable’s distribution. Interpret the standard deviation (describe what the standard deviation measures and what it tells you about your variable).

Statistics (3pts) Using question 14 (Q14) [How would you best identify yourself politically?]: (a) Create a frequency table that shows counts/frequencies. Include a column count total. Remember, Categories and titles should be correctly labeled (that is, categories should not be labeled “1”,”2”,”3”, etc). (b) Draw a bar chart for this distribution. Remember, Categories and titles […]
