Answer:
The probability that sample mean differ the true greater than 2.1 will be 2.8070 %
Step-by-step explanation:
Given:
Sample mean =46 dollars
standard deviation=8
n=53
To Find :
Probability that sample mean would differ from true mean by greater than 2.1
Solution;
<em>This sample distribution mean problem,</em>
so for that
calculate Z- value
Z=(sample mean - true mean)/(standard deviation/Sqrt(n))
Z=-2.1/(8/Sqrt(53))
Z=-2.1*Sqrt(53)/8
Z=-1.91102
Now for P(X≥2.1)=P(Z≥-1.91102)
Using Z-table,
For Z=-1.91
P(X>2.1)=0.02807
Answer:
y = x + 1
Step-by-step explanation:
Since slope is 1, then the equation will be formatted as y = x+b, since m is 1. Now we need to solve for b, since we're given a coordinate that is on the line, replace x and y for these two points to solve for b.
y = x + b (subsitute)
-1 = -2 + b (add 2 to both sides)
1 = b
So your final equation is y = x + 1.
