You construct a​ 95% confidence interval for a population mean using a random sample. the confidence interval is 24.9less thanmu
svet-max [94.6K]
No. It is not that the probability that \mu is in the interval is 0.95 rather we are 95% confident that the true mean of the population will be in the stated interval.

Confidence interval does not specify the probability of the occurrence of a population mean in an interval, rather it specifies the level of confidence on the interval of occurrence of the population mean.

An empty shipping box weighs 250 grams. The box is then filled with T-shirts. Each T-shirt weighs 132.5 grams.  The equation  re
just olya [345]

Answer:

<u>Equation:</u>

<u>250 + 132.5y = x</u>

<u>Solution for solving for x:</u>

<u>x = 250 + 132.5y</u>

<u>Solution for solving for y:</u>

<u>y = (x - 250)/132.5</u>

<u>In this situation, the solutions mean that the equation is linear or first grade because the solutions can be calculated in any of the following four forms:</u>

<u>1. Adding the same number to both sides</u>

<u>2. Subtracting the same number from both sides </u>

<u>3. Multiplying both sides by the same number </u>

<u>4. Dividing both sides by the same number</u>

Completing the question and statement correctly:

The equation  represents the relationship between the quantities in this situation, where x is the weight, in grams, of the filled box and y the number of shirts in the box.

Step-by-step explanation:

1. Let's review all the information provided to us to answer the question correctly:

Weight of an empty box = 250 grams

Weight of each T-shirt = 132.5 grams

2. Name two possible solutions to the equation that represent the relationship between the quantities in this situation, where x  is the weight, in grams, of the filled box and y the number of shirts in the box. What do the solutions mean in this situation?

x = weight, in grams, of the filled box

y = number of shirts in the box

Equation:

250 + 132.5y = x

Solution for solving for x:

x = 250 + 132.5y

Solution for solving for y:

y = (x - 250)/132.5

In this situation, the solutions mean that the equation is linear or first grade because the solutions can be calculated in any of the following four forms:

1. Adding the same number to both sides

2. Subtracting the same number from both sides

3. Multiplying both sides by the same number

4. Dividing both sides by the same number
