Answer: 0.5467
Step-by-step explanation:
Let X be the random variable that represents the income (in dollars) of a randomly selected person.
Given :
Sample size : n=350
z-score :
To find the probability that the sample mean would differ from the true mean by less than 22 dollars, the interval will be
For x=15429
For x=15473
The required probability :-
Hence, the required probability is 0.5467.
Answer:
y=-1x+3
Step-by-step explanation:
Slope intercept form: y=mx+b
x intercept (3,0)
y intercept (0,3)
start subbing in numbers from one of the points. I'm using hte x intercept so it would be (0,3). m = slope
y=mx+b
3=-1*0+b
3=0+b
b=3
so now that you know what b and the slope is,
y= -1x+3
