Answer:
within ±1.96 standard deviations of the sample mean
Step-by-step explanation:
A 95% confidence interval is found using the formula C = 1 - α, and some other stuff, but let's focus on that for now. Using the formula:
.95 = 1 - α
α = .05
If α = .05, that means a 2-sided confidence interval would be found using the sample mean and the Z-score Z(subscript α/2), or Z.₀₂₅ because α AKA .05 divided by 2 = .025. From there, you take this either to your calculator or a Z-table (or perhaps you have a chart that lists the common CI values), and see that for the area to be .025 beneath a standard normal curve, your Z value is ±1.96 ("plus or minus" because we're considering a 2-sided confidence interval).
The answer is <span>A. 142.
After a profound research, I found out that the wheel numbers are:
25, 80, 60, 20, 100, 500, 150, 200.
To calculate h</span><span>ow many cans of turtle wax can the game show expect to give out per player in the long run, we need to calculate the mean of the numbers on the wheel:
</span>
<span>
</span>⇒ <span>x </span>≈ 142
I think it’s b because the evidence points to it
Hey,
ok so the area of a rectangle is the product of the two sides. One side is the height of the can, the other side is the perimeter of the circle, since the label wraps once around the can. So the area of the rectangle is (2 pi r)* h. Add those two parts together and you have the formula for the surface area<span> of a cylinder.
so </span>To find the surface area, first multiply the length by the width to find the area. Since a cube is made up of six perfect squares, multiply the are aby six. That each measure four. Plug four into the formula to find the <span>surface area
So the formula would be </span><span>SA=2(LW+LH+WH</span>
so area a^2+4=98^
So it is C
h
