D: "The trend in the data for trial 1 shows that plants grow taller if given more fertilizer."

Explanation:

Trial 1  indicates that plants increase in height when given more fertilizer.

The standard deviation of the ages of this breed of dog is approximately 4.4 years.

To find the standard deviation, we can use the concept of z-scores and the cumulative distribution function (CDF) of a standard normal distribution. Let's denote the average age as μ (mu) and the standard deviation as σ (sigma).

Given that the average age of the breed is 19.5 years, we can set μ = 19.5. We are also given that 20% of the dogs are older than 22.6 years. Using the z-score formula, we can calculate the z-score corresponding to this percentile:

z = (x - μ) / σ

Where x is the given value (22.6 years) and z is the z-score. Rearranging the formula, we can solve for σ:

σ = (x - μ) / z

Plugging in the values, we have:

σ = (22.6 - 19.5) / z

To find the z-score corresponding to the 20th percentile, we can use the inverse CDF of the standard normal distribution. Using statistical software or a z-table, we find that the z-score corresponding to the 20th percentile is approximately -0.84.

Substituting the values, we get:

σ = (22.6 - 19.5) / -0.84 ≈ 3.7 / -0.84 ≈ -4.4

Soo um for the first and second one both are basicallys are d because of how in both values its not prevalent always that itll be 95% bcuz most of the time it has a value of X squared minus the b squared formula which u might have learnt there and if u see 95% from justt that, its not always gonna be a 95CI for the value .

Ok bye hope this helps

The first and second examples are both essentially d because it is not always the case that the values will be 95% because most of the time they have a value of X squared minus the b squared formula, which you may have learned there.

The "difference of squares formula" is another name for the a2 - b2 formula. Without calculating the two squares, the a square minus b square is utilized to determine their difference.

If you see 95% from just that, it is not always going to be a 95CI for the value.

The argument for why (a + b) is the value of a2 - b2 (a - b). Let's think about the image above. Consider the two squares with sides a and b, respectively. As seen in the image below, this can alternatively be shown as the product of the areas of two rectangles.

Therefore, The first and second examples are both essentially d because it is not always the case that the values will be 95% because most of the time they have a value of X squared minus the b squared formula, which you may have learned there.

Answer:

To find a 90 percent confidence interval for the population mean of the workers' monthly income in the factory, you can use the formula:

Confidence interval = sample mean ± (critical value * standard error)

First, you need to find the critical value corresponding to a 90 percent confidence level. Since the sample size is large (n = 100), we can use the Z-distribution. For a 90 percent confidence level, the critical value is approximately 1.645.

Next, you calculate the standard error, which is the standard deviation of the sample divided by the square root of the sample size:

Standard error = standard deviation / √(sample size)

Standard error = 20 / √(100)

Standard error = 20 / 10

Standard error = 2

Now you can substitute the values into the confidence interval formula:

Confidence interval = 400 ± (1.645 * 2)

Calculating the confidence interval:

Lower bound = 400 - (1.645 * 2) = 400 - 3.29 = 396.71

Upper bound = 400 + (1.645 * 2) = 400 + 3.29 = 403.29

The 90 percent confidence interval for the population mean of the workers' monthly income is approximately 396.71 to 403.29 birr.

Explanation:

Interpretation: We are 90 percent confident that the true population mean of the workers' monthly income in the factory falls within the range of 396.71 to 403.29 birr. This means that if you were to take multiple samples and calculate confidence intervals for each sample, approximately 90 percent of those intervals would contain the true population mean.

This means that if he drivess for an hour he will cover 45 miles but here he only travel for 11 minute

Changing mph into mpm we get 0.75 mile per minute

Multiply 0.75 by 11

We get 8.25 mean he has moved 8.25 mile

As the total distance is 24

So subtract it 24- 8.25= 15.75

He will have to walk 15. 75miles more mean he will have to travel 21 min. More

The cost of the Costa Rica and Columbian coffee are $200 and $150 respectively

Let us recall that we are told that a  coffee shop sells special blend of coffee that comes in a 100-pound bag and costs $3.50 per pound. It is a mix of coffee from Costa Rica at $4 per pound and Columbian at $3 per pound.

Let the number of pounds of the  Costa Rica coffee be x and the number of pounds of the Columbian coffee be y.

Given that;

x + y = 100 ------- (1)

4 x + 3 y = 350 ------- (2)

y = 100 - x ----(3)

Substitute (3) into (2)

4x + 3(100 - x) = 350

4x + 300 - 3x = 350

x + 300 = 350

x = 350 - 300

x = 50

From(1)

50 + y = 100

y = 50

Then;

Cost of the Costa Rica coffee = 4(50) = $200

Answer:

Family of origin can have a lasting impact on a person's life. It can shape their worldview, affect their relationships, and influence their emotional well-being.

Explanation:

Family of origin refers to the family into which a person is born or raised. It includes the people who are directly related to a person by blood, such as parents, siblings, grandparents, and sometimes extended family members like aunts, uncles, and cousins. It can also include people who are not related by blood but are considered part of the family, such as stepparents or adoptive siblings.

There are several ways in which a family of origin can influence a person:

Identity formation: Family of origin plays a critical role in shaping a person's sense of identity. It is where a person learns about their culture, values, beliefs, and traditions. The family also provides a framework for understanding oneself in relation to others, which can shape self-esteem and confidence.

Relationship patterns: Family of origin influences a person's relationship patterns and expectations. It can affect how a person communicates, resolves conflicts, and forms attachments. People often bring these patterns into their adult relationships, and if they are unhealthy, they can lead to difficulties in forming and maintaining healthy relationships.

Emotional well-being: Family of origin also has a significant impact on a person's emotional well-being. Positive experiences, such as love, support, and security, can contribute to a sense of emotional stability, while negative experiences, such as abuse or neglect, can have lasting effects on mental health and emotional regulation.

Overall, family of origin can have a lasting impact on a person's life. It can shape their worldview, affect their relationships, and influence their emotional well-being.
