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,
Answer:
Step-by-step explanation:
Read simply, it is m + (r - 2). It is a very clear statement, so you can depend on the answer.
Answer:
1:4
Step-by-step explanation:
