The amounts (in ounces) of juice in eight randomly selected juice bottles are: 15.8, 15.6, 15.1, 15.2, 15.1, 15.5, 15.9, 15.5 co

julia-pushkina [17]

The confidence interval is given by the formula:
m +/- z·(σ/√n)

First, compute the mean:
m = (<span>15.8 + 15.6 + 15.1 + 15.2 + 15.1 + 15.5 + 15.9 + 15.5) / 8
= 15.463

Then, compute the standard deviation:
</span>σ = √[∑(v - m)²/n]
= 0.287

The z-score for a 95% confidence interval is z = 1.96.

Now you can calculate:
m + z·(σ/√n) = 15.463 + 1.96·(0.287/√8)
= 15.463 + 0.199
= 15.662

m - z·(σ/√n) = 15.463 - 1.96·(0.287/√8)
= 15.463 - 0.199
= 15.264

Therefore the confidence interval is (15.264, <span>15.662) and the correct answer is E) none of the above.</span>

Find the area. simplify your answer.

PolarNik [594]

Answer:

The area is:

$2 {x}^{2}$

Step-by-step explanation:

Area of this figure is simply the product of the base and the height, as it just happens to be a slanted or inclined rectangle.

Therefore:

$a = 2x (x) = 2 {x}^{2}$

Help me with this!!!

PIT_PIT [208]

Answer:

Total probability value is 1

P(green) = 0.2 , P(brown) = 0.54

Given P(red) = P(yellow) = x

Total Probability = P(green) + P(Brown) + x + x

1 = 0.2 + 0.54 + 2x

1 - 0.74 = 2x

x = 0.13

P(red) = P(yellow) = 0.13

Now number of times it landed on each color :

$On \ red :\\P(red) = \frac{number \ of \ times \ on \ red}{1200} \\\\0.13 *1200 = number \ of \ times \ on \ red\\number \ of \ times \ on \ red\\ = 156\\$

Since P(red) = P(yellow) , the number of time on yellow and red are same.

$On \ yellow :\\number \ of \ times \ on \ yellow = 156$

$On \ green :\\P(green ) = \frac{number \ of \ times \ on \ green}{1200}\\\\0.2 *1200 = number \ of \ times \ on \ green\\\\number \ of \ times \ on \ green = 240$

$On \ Brown : \\P(brown) = \frac{number \ of \ times \ on \ brown}{1200}\\\\0.54 *1200 = number \ of \ times \ on \ brown\\number \ of \ times \ on \ brown = 648$

Answer :

Red 156

Green 240

Brown 648

Yellow 156
