Answer:
Option 1 - Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation.
Step-by-step explanation:
Given : Process
Step 1: 4x + 2 = 10
Step 2: 4x = 8
To find : Which justification describes the process?
Solution :
From step 1 to step 2, we subtract 2 both sides
Step 1: 4x + 2 = 10
Subtracting 2 both side,
⇒ 4x + 2-2 = 10-2
Step 2: 4x = 8
So, The best justification is 'Using the Subtraction Property of Equality, 2 is subtracted from both sides of the equation'.
Therefore, Option 1 is correct.
Answer: 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where 
= Population standard deviation.
n= sample size
= Sample mean
z* = Critical z-value .
Given : 
n= 49
Two-tailed critical value for 95% confidence interval = 
Then, the 95% confidence interval would be :-
Hence, the 95% confidence interval for estimating the population mean 
:
