I hope its right edg 2020
Answer:
1, 3, 5 or 1, 2, 3 I think? Sorry if its not
Let
n = number of data
s = standard deviation (sample)
S = standard deviation (population)
The working equations is

To find

, : (1 - 0.90)/2 = 0.05
To find

, : 1 - 0.05 = 0.95
Degrees of freedom = n-1 = 24 - 1 = 23
This is shown in the figure attached. Since there is no row for df=23, we interpolate. Thus,
Substitute all values,

Thus the answer is,
I think it is 51.5 because I did 2x - 24 + x - 2 + x = 180 and then collected like Yerma and equaled it to 180.
