Answer:

Box <u>C</u> is the large box because it has the volume of <u>34.3ft</u>. Box <u>A</u> is the medium box because it has the volume of <u>22.5ft</u>. Box <u>B</u> is the smallest box because it has the volume of <u>18ft</u>.

Step-by-step explanation:

Step 1) the formula for Volume is Length x width x Height

step 2) find the volume of Box A (12 times 3 and 1/2 times 1 and 1/4 = 22.5)

step 3) find the volume of box B ( 6 times 4 times .75 = 18)

step 4) find the volume of box C (3.25 times 3.25 times 3.25 = 34.3)

step 5) determine which box has the largest volume (Box C is the largest)

step 6) determine which box is the second largest/or medium box (Box A is the medium box)

step 7) determine which box is the smallest one (box B is the smallest)

step 8) fill in the blanks

Hypothesis Testing for Means with Small Samples
Scorpion4ik [409]

Answer:

Step-by-step explanation:

Hello!

The variable of interest is

X: volume of root beer in a Windsor Bottling Company can.

A sample of n=24 cans was taken and their contents measured, resulting:

X[bar]= 11.4 oz

S= 0.62 oz

Assuming that the variable has a normal distribution X~N(μ;σ²), the parameter of interest is the average contents of the root beer cans of the Windsor Bottling Company (μ)

The claim is that the population mean content of the cans is different from 12 oz, symbolically: μ ≠ 12

The statistical hypothesis (Null and alternative) have to be complementary, exhaustive and mutually exclusive. The null hypothesis is the "no change" hypothesis and always carries the "=" sign.

If the claim is μ ≠ 12, its complement is μ = 12, the expression carrying the "=" sign will be the null hypothesis and its complement will be the alternative hypothesis:

H₀: μ = 12

H₁: μ ≠ 12

α: 0.05

To test the population mean of this normal population, you have to apply a one sample t-test, with statistic:

t= \frac{X[bar]-Mu}{\frac{S}{\sqrt{n} } } ~t_{n-1}

t_{H_0}= \frac{11.4-12}{\frac{0.62}{\sqrt{24} } } = -4.74

This test is two-tailed, using the critical value approach, you have to determine two rejection regions. Meaning, you'll reject the null hypothesis to small values of the statistic or to high values of the statistic.

t_{n-1;\alpha /2}= t_{23;0.025}= -2.069

t_{n-1;1-\alpha /2}= t_{23;0.975}= 2.069

The decision rule is:

If t_{H_0} ≤ -2.069 or if t_{H_0} ≥ 2.069, then you reject the null hypothesis.

If -2.069 < t_{H_0} < 2.069, then you do not reject the null hypothesis.

The value is less than the left critical value, the decision is to reject the null hypothesis.

Then you can say that with a 5% significance level, there is significant evidence to reject the null hypothesis, then the average amount of root beer of the Windsor Bottling Company is different from 12 oz, this means that the claim about the amount of root beer in the cans is correct.

I hope it helps!

A cafeteria serves 340 cups of milk each day. How many pints of milk does the cafeteria serve each day?
poizon [28]

Answer:

170 pints

Step-by-step explanation:

Since 1 cup is equivalent to half of a pint, you would divide the amount of cups by two to get your answer. 340/2=170

Scorpion4ik [409]

Answer:

465 miles

Step-by-step explanation:

So you have the ratio 1 cm: 110 mi, so you can multiply both sides of this ratio by 4.5 to get

4.5 cm: 465 mi
