A two-sample t-test for a difference in means will be conducted to investigate mean gasoline prices in two states. From each state, 45 gasoline stations will be selected at random. On the same day, the price of regular gasoline will be recorded for each selected station and the sample mean price for each state will be calculated.

Answers

Answer 1

Answer:

All conditions have been met

Explanation:

The data are being collected using a random method. The sample sizes are large enough (both 45) to support the assumption of normality for the sampling distribution of the difference in sample means. Also, it is reasonable to assume that 45 gasoline stations is less than 10 percent of all the gas stations in each state.

Answer 2

Answer:

Yes, all conditions have been met.

What is the probability that it will take exactly 4 selections to get a B or better? What is the probability that it will take more than 3 selections to get a B or better?

Answers

Explanation:

Probability of exactly 4 selections

How many grams of chlorophyll, C55H72MgN4O5, a nonvolatile, nonelectrolyte (MW = 893.5 g/mol), must be added to
174.9 grams of ethanol to reduce the vapor pressure to 53.25 mm Hg ?
ethanol = CH3CH2OH = 46.07 g/mol.
___g chlorophyll?

Answers

Answer:

88.19 g

Explanation:

From Raoult's law;

P° - P/P° = XB

XB = mole fraction of solute = number of moles of solute(n)/number of moles of solute(n) + number of moles of solvent (N)

But N>>n

So,

XB = number of moles of solute/number of moles of solvent

Number of moles of solute = mass of solute (WB)/molar mass of solute (MB)

number of moles of solvent = mass of solvent (WA)/molar mass of solvent (MA)

Hence;

P° - P/P° = WB/MB * MA/WA

WB = (P° - P/P°) (MB * WA/MA)

Substituting values;

WB = (54.68 - 53.25/54.68) * (893.5 * 174.9/46.07)

WB = 88.19 g

A company makes paper labels for paint cans. As shown below, each can is in the shape of a cylinder with a height of 9in and a diameter of 8in. The paper label is wrapped around the can and covers only the side of the can (not the top or bottom). If the company makes 15 labels, how many square inches of paper will be needed? Use 3.14 for π, and do not round your answer.

Answers

Answer:

Answer: 4,772.8 cm2

Explanation:

The company will need 3,583.2 square inches of paper to make 15 labels.

What is cylinder?

Traditionally, a cylinder was a three-dimensional solid, one of the most fundamental curvilinear geometric shapes. It is a prism with a circle as its base in elementary geometry.

The formula for circumference is:

Circumference = π × diameter

Circumference = 3.14 × 8in

Circumference = 25.12in

So the label will need to be 25.12 inches long.

The height of the label will be the same as the height of the can, which is 9 inches.

To find the total area of the paper needed for 15 labels, we need to multiply the length of each label by its height and then multiply that by the number of labels:

Total area = length × height × number of labels

Total area = 25.12in × 9in × 15

Total area = 3,583.2 square inches

Thus, the answer is 3,583.2 square inches.

The tipping over dominoes game most represents a wave. Thus, option D is correct.

What is a wave?

An alteration or disruption that causes energy to be transferred gradually from one point to another in a medium; it may involve an elastic deformation or a change.

The game Tipping Over Dominoes most likely represents a wave. This game involves lining up the dominoes in sequence and pushes the starter. This will cause a delightful cascade of dominoes to fall across the push-up site to the final domino.

Every domino goes down with the wave's direction in mind. The wave of sound is a better physical illustration. The changes in the position of the dominoes as they fall have both horizontal as well as vertical elements.

Therefore, option D is correct.

In a certain region, many of the residents are employed by the oil industry. Economists in the region investigated the difference between the salaries of those who work in oil-field jobs and those who work in non-oil-field jobs. Salaries were recorded for a random sample of 84 workers from the 1,200 oil-field workers and a random sample of 72 workers from the 50,000 non-oil-field workers in the region. A 95 percent confidence interval for μO−μN, where μO is the mean salary of all jobs of oil-field workers and μN is the mean salary of all jobs of non-oil-field workers, will be constructed. Have the conditions for inference with a confidence interval been met?

Which of the following is produced when sugar is processed in an animal cell

Answers

Answer:

Carbon dioxide

Explanation:

Glycolysis which is the breakdown of sugar in living things, is a metabolic process that helps to release energy. Pyruvate is a product of this process that involves ten steps. After glycolysis has occurred, pyruvate is moved to the cellular powerhouse (the mitochondria) in the presence of oxygen.

There, carbon dioxide is extracted from pyruvate and acetyl coenzyme A is generated. This shows that carbon dioxide is produced when sugar is processed in animal cells.
