Question

The data list shows the cost, in dollars, of different brands of sneakers at a shoe store.

44.99, 59.99, 32.30, 65.00, 52.59

What is the population standard deviation, to the nearest tenth, of the data (assuming this is all of the data)?

Answer 1

use the population standard deviation formula

nice website to do it

Answer 3

Reposting the same question again and again won't get you different answers

Answer 4

\(\sigma =\sqrt{ \dfrac{\sum(x_i-\mu)^2}{N}}\)

where
\(\sigma\) = population standard deviation
\(\sum\) = the sum from 1 to N
\( x_i\) = each individual data point
\(\mu\) = mean of the data list
\( N\) = total number of data points

so to first find the population standard deviation, can you tell me what the average or mean is?

44.99, 59.99, 32.30, 65.00, 52.59

How many numbers do we have? That's going to be our N.
Add them all and divide by that number N. That will be our mean.

What do you get?

Answer 5

Just answer my questions and we can find the standard deviation one step at a time

How many numbers are in your list:
44.99
59.99
32.30
65.00
52.59

Can you count how many numbers there are?

Answer 6

Then add all those numbers up
44.99 + 59.99 + 32.30 + 65.00 + 52.59

What do you get?

And then divide the number that you get now by how many numbers there were in your list

Answer 7

That's going to give us your \(\mu\) or mean

Once you answer those few questions I asked you above, we can move to the other variables and complete your question :)
