**Answer:**

The probability that the sample mean will be within 0.5 of the population mean is **0.3328**.

**Step-by-step explanation:**

It is provided that a random variable *X* has mean, *μ* = 50 andstandard deviation, *σ* = 7.

A random sample of size, *n* = 36 is selected.

According to the Central Limit Theorem if we have a population with mean μ and standard deviation σ and we take appropriately huge random samples (n ≥ 30) from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.

Then, the mean of the distribution of sample mean is given by,

And the standard deviation of the distribution of sample mean is given by,

So, the distribution of the sample mean of *X* is N (50, 1.167²).

Compute the probability that the sample mean will be within 0.5 of the population mean as follows:

Thus, the probability that the sample mean will be within 0.5 of the population mean is **0.3328**.

To approximate the probability that the **sample **mean will be within 0.5 of the population mean, we can use the Central Limit Theorem. This theorem states that the sampling distribution of the sample means will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough. To calculate the probability, we need to find the standard error of the **mean **(SE), calculate the z-score for the upper bound of 0.5 deviations above the mean, and then find the cumulative probability corresponding to that z-score using a z-table or calculator.

To find the approximate probability that the sample mean will be within 0.5 of the population mean, we can use the Central Limit Theorem. According to the Central Limit Theorem, the sampling **distribution **of the sample means will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough (typically n ≥ 30).

- Calculate the standard error of the mean (SE) using the formula SE = σ/√n, where σ is the standard deviation of the population and n is the sample size. In this case, σ = 7 and n = 36, so SE = 7/√36 = 7/6 = 1.1667.
- Next, calculate the z-score corresponding to the upper bound of 0.5 deviations from the mean by using the formula z = (X - μ)/SE, where X is the value 0.5 deviations above the mean (50 + 0.5 = 50.5 in this case), μ is the mean of the population, and SE is the standard error of the mean. The z-score for 0.5 deviations above the mean can be calculated as z = (50.5 - 50)/1.1667 ≈ 0.4292.
- Finally, use a z-table or a calculator to find the probability corresponding to the z-score found in the previous step. The probability can be determined by subtracting the cumulative probability of the lower bound (z = -0.4292) from the cumulative probability of the upper bound (z = 0.4292). This can be expressed as p = P(Z < 0.4292) - P(Z < -0.4292).

Using a standard normal distribution table or a calculator, the approximate probability that the sample mean will be within 0.5 of the population mean is the difference between the cumulative probabilities of the upper and lower bounds found in step 3.

**Answer:**

$5.25

**Step-by-step explanation:**

$26.25 divided by 5 is $5.25

**Answer:**

**$5.25** for 1 lb of chicken

**Step-by-step explanation:**

**How did I get $5.25??** 26.25 / 5 =** 5.25**

1 * 5.25 = $5.25

2 * 5.25 = $10.50

3 * 5.25 = $15.75

4 * 5.25 = $21

5 * 5.25 = **$26.25**

Yes, it is proportional. The answer would be B.

**Answer:**

one pencil cost $0.15

**Step-by-step explanation:**

Answer: $0.15 and/or 15 cents

Explanation: If you use common sense, information provided, and basic math, you notice that after 2 pencils were removed the total cost dropped 30 cents/$0.30; therefore, after 2 pencils are taken away the cost drops 30 cents and to find the price for one pencil all you have to do is divide 30/2 and you get 15 cents and/or $0.15.
