Answer: The required confidence interval would be (2.72,2.89)
Step-by-step explanation:
Since we have given that
Mean = 2.8 pounds
Standard deviation = 0.24 pounds
n = sample size = 16
We need to find the 80% confidence interval for the mean waste.
z=1.341
So, the confidence interval will be
Hence, the required confidence interval would be (2.72,2.89)

Answer:
The system of equations is:
x + y = 15
xy = 15
Step-by-step explanation:
solve the first for y and substitute in the second:
y = 15-x
x(15-x) = 15
15x - x� = 15
15x - x� - 15 = 0
-x� + 15x - 15 = 0
x� - 15x + 15 = 0
Answer:
36
Step-by-step explanation:
3*2=6
6^2 is 36
If the train travels 744 miles in 3 hours then to determine the unit rate the train is traveling per hour you have to divide the miles by the hours, in this case (744 miles)/(3 hours). The final result concludes as 248 miles per hour.
