Given data is a= [3,7,2,4,8,4,1,3]
c. The mean of a is:
a-bar=(3+7+2+4+8+4+1+3)/8
=32/8
a-bar=4
The average value indicates that the center of the data is 4, around which the observations are spread.
If these numbers represented the rolls of a 10 sided dice, then on an average we get 4 on the upper face.
given that the data set is a=[3,7,2,4,8,4,1,3] compare to what you got above. How would you...
4) (10 pts) You are doubtful about the fairness of a six-side die. It's expected that 50% of the time you should get the numbers 1, 2, or 3 a) After 20 rolls, what is the standard deviation you'd expect of the number of times you get 1, 2, or 3? b) After 20 tosses you find that you got these numbers only 40% of the time. Do you make an accusation? many rolls would it take for you to...
How do you find the standard deviation of a data set of numbers? I know the median, and the upper and lower quartile numbers. I am making a box plot and need to know how to graph that on a box plot as well. For example let us say the numbers are 1,2,3,4,5,6,7,8,9. How would you find the standard deviation?
Based on the regression line above, what amount would you
predict for local spending if a state spends $40 billion? What
might be some reasons that using that prediction would give you
hesitation?
The data given in tab one can be used to compare education spending by state. We cannot use the data as given, however. For example, to compare Texas and Vermont purely on total amount spent would give a false impression of how much each state spends on...
Suppose that you have two sets of data to work with. The first set is a list of all the injuries that were seen in a clinic in a month's time. The second set contains data on the number of minutes that each patient spent in the waiting room of a doctor's office. You can make assumptions about other information or variables that are included in each data set. For each data set, propose your idea of how best to...
if
you could include how you got the answer that would be great

Use what you need of the following set of information to answer the question: S0 = $1.1420/€ S0 = £0.7776/$ S0 = $1.2860/£ E (S1 (3-months)) = $1.1280/€ F3-months = $1.1590/€ Where: € = euro; £ = British pound; E ( ) = Expected. If you want to know the spot value of the euro in terms of the British pound from the information given above, how would you find out? Show calculations. If you want to...

GIVEN: Consider the following data (which is also the data that you will be using in Problem #7 below): 26, 25, 35, 34, 27, 31, 25 (a) If you were to construct a normal probability plot by hand for the above data, what are the numerical values (in order) of the first five numbers that would go on the x-axis? Separate your answers with a comma. For example, if your data was the same as the data in the first...
What Indian and US data would you need to compare Indian and US per capita income using PPP? How would you use this data?
If you could please explain and give
detailed on how you got this answer thanks.
What would be the final Cu^+ concentration in a solution that is originally 0.10 M in both Cu^+ and Pb^2+, such that the minimum I^- concentration is present to just precipitate both Cut and Pbl2? KsP (Cul) = 5.1 Times 10^-12 and KsP (Pbl2) = 1.4 Times 10^-8
