Answer. Answer: 27 is three fourths of what number? Solution.

Approach: If four numbers a, b, c and d are in proportion then a:b = c:d. The solution is to sort the four numbers and pair up the first 2 together and the last 2 together and check their ratios this is because, in order for them to be in proportion, the product of means has to be equal to the product of extremes.

A proportion is an equality of two ratios. We write proportions to help us find equivalent ratios and solve for unknown quantities. A rate is the quotient of a ratio where the quantities have different units.

A population proportion is a fraction of the population that has a certain characteristic. For example, let’s say you had 1,000 people in the population and 237 of those people have blue eyes. The fraction of people who have blue eyes is 237 out of 1,000, or 237/1000.

A proportion is simply a statement that two ratios are equal. It can be written in two ways: as two equal fractions a/b = c/d; or using a colon, a:b = c:d.

Interpretation. Use the p-value to determine whether the population proportion is statistically different from the hypothesized proportion. To determine whether the difference between the population proportion and the hypothesized proportion is statistically significant, compare the p-value to the significance level.

To calculate the test statistic, do the following:

1. Calculate the sample proportions. for each sample.
2. Find the difference between the two sample proportions,
3. Calculate the overall sample proportion.
4. Calculate the standard error:
5. Divide your result from Step 2 by your result from Step 4.

To calculate the confidence interval, we must find p′, q′. p′ = 0.842 is the sample proportion; this is the point estimate of the population proportion. Since the requested confidence level is CL = 0.95, then α = 1 – CL = 1 – 0.95 = 0.05 ( α 2 ) ( α 2 ) = 0.025.

A true proportion is an equation that states that two ratios are equal. If you know one ratio in a proportion, you can use that information to find values in the other equivalent ratio.

: a proportion of two variable quantities when the ratio of the two quantities is constant.

The term direct proportion means that two (or more) quantities increase or decrease in the same ratio. For example, in the purple paint mixture, the ratio of blue to red of 4:3. This does not necessarily mean we every mixture would have 4 red and 3 blue cans. It does mean we would have 4 red for every 3 blue cans.

In a direct proportion, the ratio between matching quantities stays the same if they are divided. (They form equivalent fractions). In an indirect (or inverse) proportion, as one quantity increases, the other decreases. In an inverse proportion, the product of the matching quantities stays the same.
