Answer: 3.190
Step-by-step explanation:
If the population distribution is normal, and population standard deviation is unknown, then
The test statistic is given by :-
, where = sample mean , = population mean , n= sample size, s= sample standard deviation.
Given: = 2058
= 2044
s= 17
n= 15
Test statistic:
Hence, the value of the test statistic is 3.190 [Rounded to the three decimal places.]
-(7x + 4)- 2x + 2 = 52
Distribute the negative sign:
-7x -4 - 2x + 2 = 52
Combine like terms:
-9x - 2 = 52
Add 2 to both sides:
-9x = 54
Divide by -9:
x = -6
Answer: x = -6
