Answer:
An appliance manufacturer gives a warranty, and 95 percent of its appliances do not require repair before the warranty expires. An organization buys 10 of these appliances. Calculate an interval that contains 95.44 percent of all the appliances that will not require repair.
A. [8.12, 10.88]
B. [7.43, 11.57]
C. [8.81, 10.19]
D. [8.55, 10.45]
Step-by-step explanation:
We can calculate the confidence interval for a proportion p = 0.95 and a sample size n = 10.
Note that the critical value for 95.44% confidence is 1.9991. Z-score table.
Between 81.22% and 108.78% of 10 units is 8.12 and 10.88 units. Therefore the confidence interval is: (8.12, 10.88).
Answer: [ 8.12 , 10.88 ]
Answer:
Step-by-step explanation:
the y intercept determines where you are going to start and then your m or your slope tells you how many units up or down and left and right you are going to go or you rise over run in this case 2/1
so you start at (0,2) and then move 2 up and one to the right
and you go 2 units down and 1 to the left
Answer:
Step-by-step explanation:
The equation for this free fall problem is
where h(t) is the height of the pebble from the ground at any time t. If we are looking for the time it takes the pebble to hit the ground, knowing that at ground level the height is 0, we set the quadratic equal to 0 and solve for t:
and
and
so
t = -8, 8
Since time will never be negative,
t = 8 seconds
