Solution :
a). Standard error of sample mean = 
= 0.1290994
The observed mean point be 
Test statistics z = 
For the left one sided test, critical value of z to reject 
We reject 
when test statics z < -1.64
b). Value of z < -1.64
∴ we reject when 
c). The probability of rejecting when 
,
There are 180 degrees in total inside a triangle.
If something is equilateral that means that all the angles are equal.
180/3 equals 60 degrees.
That means that all angles of an equilateral triangle are always equal to each other and if you must know, are 60 degrees
Rewrite the function as an equation.
y= 3 x −3
The slope-intercept form is y=mx + b, where m is the slope and b is the y-intercept.
y=mx + b
Find the value of m and b by using the form y = mx + b
The slope of the line is the value of m, and the y-interept is the value of b.
Slope:3
Y-intercept: -3
Answer:
8 Hours
Step-by-step explanation:
First, you have to subtract the 25$ because we already know that that is a stable value (meaning it will not change)
Then, you have to divide 440 by 55 to get an answer of 8 hours for the session :D
