Answer:
Step-by-step explanation:
The confidence interval gives a range of values that could contain the population mean.
Confidence interval is written as
Sample mean ± margin of error
Confidence interval does not express probability.
Given that the sample mean home price for city A is $189500 and the sample mean home price for city B is $185000, the difference in the sample mean home prices for both cities is
189500 - 185000 = $4500
Since the margin of error for 95% confidence interval for the difference in average home price between the two cities (A-B) to be $3400, then
The upper limit of the confidence interval is
4500 + 3400 = $7900
The lower limit of the confidence interval is
4500 - 3400 = $1100
Therefore, the correct conclusion is
Beatrice can be 95% confident that the average home price is between $1100 and $7900 more in city A than in city B.
Answer:
63.75
Step-by-step explanation:
2^4=16
16x4=64
64-2/8=63.75
because 2/8 can be reduced to 1/4 and 1/4 in decimal form is 0.25.

Answer:
y= -5/2x -1
Step-by-step explanation:
Answer:
The slope will be 0
Step-by-step explanation:
Once you do the slope formula which is y2 - y1 over x2-x1
You will get 0/3 in this case. So if the numerator is a 0 the slope will also be 0.
