The following is a list of 10 measurements: after adding and sub all 10 numbers I came up with a -29. Now it wants the sum 10/i,i than xi over 32.
Do I x -29 and the 32 or do I divide. This is were I get very confused. I am sorry to ask again but I never taken statistic oh I did some 50 years ago.
Thank you
I can help you understand how to calculate the expression you mentioned.
The expression you provided is: (10/i)i(xi/32).
Let's break it down step by step:
1. "10/i" means you need to divide 10 by the value of i.
2. "i" is the index or position of the measurement. Since you mentioned you have a list of 10 measurements, i can take values from 1 to 10.
3. "(xi/32)" means you need to divide the value of xi by 32.
4. xi represents the i-th measurement in your list.
Now, let's understand the calculation you need to perform:
1. Start by calculating (10/i). For each value of i from 1 to 10, divide 10 by the value of i. The result will be a set of values: (10/1), (10/2), (10/3), ..., (10/10).
2. Next, calculate xi/32 for each value of xi from your list. Replace xi with the actual value of each measurement. The result will be a set of values: (x1/32), (x2/32), (x3/32), ..., (x10/32).
3. Now, multiply the corresponding values you obtained in step 1 and step 2. For example, multiply (10/1) with (x1/32), (10/2) with (x2/32), and so on. You will have a set of products: [(10/1)(x1/32)], [(10/2)(x2/32)], [(10/3)(x3/32)], ..., [(10/10)(x10/32)].
4. Finally, sum up all the products you calculated in step 3. Add them together to get the final result.
To clarify, you do not need to multiply -29 with 32 or divide them. The expression you provided involves dividing 10 by i and multiplying it with xi divided by 32 for each value of i and xi.
I hope this explanation helps you in understanding the calculation involved.
