Research scientists use a standard practice called the _____ method to help them understand phenomena.
Answer:
2
Step-by-step explanation:
We have
n = 4 scores
SS = 48
For this question, we are required to find the estimated standard error
To get this, we first solve for the variance
S² = SS/n-1
= 48/4-1
= 48/3
= 16
Then S² = 16
S = √16
S = 4
Then the estimated standard error is given by:
S/√n
= 4/√4
= 4/2
= 2.
The estimated standard error is 2.
Hhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh
Answer:
Step-by-step explanation:
Let x = $ invested in 8% account
y= $ invested in 10.5% account
x + y= 12000
0.08x + 0.105y = 1145
$4600 invested in the 8% account
and $7400 invested in the 10.5%
account
