Step-by-step explanation:
From the question we are told that
The population mean is 
The sample size is 
The sample mean is 
The standard deviation is 
Generally the test statistics is mathematically represented as

substituting values


Answer:
The Answer is C.
Step-by-step explanation:
There is only one number before the decimal point, 6. 6 ones, so we already cross out A and D as incorrect. Now we have B and C. There is only two numbers after the decimal point. The first number after the point is in the tenths place. So, B is the correct answer.

Answer:
y = 2x -4
Step-by-step explanation:
The coefficient of x in the given equation is the slope of the line. A perpendicular line will have a slope that is the opposite reciprocal:
-1/(-1/2) = 2
The point-slope form of the equation of a line can be used to find the desired equation:
y -y1 = m(x -x1) . . . . . . line through (x1, y1) with slope m
For (x1, y1) = (2, 0) and m = 2, the equation is ...
y -0 = 2(x -20
y = 2x -4
Do you mean, what times 6 equals 42 ?
if that then it is 7
6x7=42
