the sample mean salary of 500 nba players is 5 million dollars. we also know that the population standard deviation is 0.7 million dollars. we want to construct a confidence interval for population mean with 95% confidence. what will be the length of our confidence interval (in terms of million dollars)?

For a dataset with a minimum value of 7, maximum value of 81, and divided into 7 classes, the class width is 11, the lower class limits are 7, 18, 29, 40, 51, 62, 73, and the upper class limits are 17, 28, 39, 50, 61, 72, 73.

(a) The class width is calculated by dividing the range (maximum - minimum) by the number of classes:

Class width = (maximum - minimum) / number of classes

= (81 - 7) / 7

= 74 / 7

≈ 10.57

Rounding to the nearest whole number, the class width is 11.

(b) To find the lower class limits, we start with the minimum value and then add the class width repeatedly to obtain the next lower class limit. Here's the calculation:

Lower class limits: 7, 18, 29, 40, 51, 62, 73

(c) The upper class limits can be found by subtracting 1 from each lower class limit, except for the last class. The last class's upper limit is the same as the last class's lower limit. Here's the calculation:

Upper class limits: 17, 28, 39, 50, 61, 72, 73

Therefore, For a dataset with a minimum value of 7, maximum value of 81, and divided into 7 classes, the class width is 11, the lower class limits are 7, 18, 29, 40, 51, 62, 73, and the upper class limits are 17, 28, 39, 50, 61, 72, 73.

The correct is b i.e; the critical value times the standard error of the sampling distribution

Given options are :

a. The biggest sampling error that can be made while maintaining a certain level of confidence.

b. the critical value multiplied by the sampling distribution's standard error

c. the discrepancy between the parameter and the point estimate.

Margin of error

In this scenario, we are given the following information: sample size (n) is 49, sample mean (P) is 50, sample standard deviation (s) is 7, null hypothesis (H₀) states that the population mean (μ) is greater than or equal to 52, and the alternative hypothesis (Hₐ) states that the population mean is less than 52.

The test statistic for this situation is the t-statistic, which measures the difference between the sample mean and the hypothesized population mean, taking into account the sample size and the sample standard deviation. It is used to assess the evidence against the null hypothesis. In this case, since the alternative hypothesis states that the population mean is less than 52, we have a left-tailed test. To calculate the t-statistic, we use the formula:

t = (P - μ) / (s / √n)

Plugging in the given values:

t = (50 - 52) / (7 / √49) = -2 / (7 / 7) = -2

Therefore, the test statistic for the provided information is -2. This value represents the standardized difference between the sample mean and the hypothesized population mean, accounting for the sample size and standard deviation. It indicates that the sample mean is 2 standard deviations below the hypothesized population mean of 52.

Answer:

Step-by-step explanation:

6c=72

We can divide by 6 on both sides and get

c=72/6

Answer:

both lori and jayden are correct

Step-by-step explanation:

first solve 72/6, you should get 12. Therefore c should be 12 since to get the number of cards in a pack you divide the total number of cards by the number of packs.
plug in 12 for the equation 6c=72

6x12 = 72 (6 being the number of packs and twelve the number of cards per pack).

After the stock's value increases by 4.5% and then falls by the same percentage, the new value would be approximately $997.975.

Let's calculate the new value of the stock after the increase and decrease.

Starting with $1,000, a 4.5% increase in value would be calculated as (4.5/100) * 1000 = $45. This brings the value up to $1,045.

Next, a 4.5% decrease in value would be calculated as (4.5/100) * 1045 = $47.025. This amount is subtracted from the increased value of $1,045.

Subtracting $47.025 from $1,045 gives us $997.975, which is slightly less than $1,000.

Therefore, after the stock's value increases by 4.5% and then falls by the same percentage, the new value would be approximately $997.975. It's important to note that this calculation assumes a simple percentage increase and decrease without considering other factors that can affect stock market fluctuations.

Step-by-step explanation:

Answer:

6,250$ is the overhead for department a

The distribution of overhead to Department A based on sales is $6250.

A recurring cost of running a firm is referred to as overhead or overhead charge. While operating expenses like material and labor, overheads could easily be linked to or recognized with any one revenue unit.

They are operating costs for a business that cannot be connected to the creation or production of a good or service. They are really the costs a business must pay to remain open, independent of how successful it is.

Department A has sales of $200,000

Department B has sales of $600,000

Therefore the ratio between the two departments will be:

200000: 600000

= 1 : 3

The overhead expense for both the department combined are $25,000

The share of department A will  be at

= 25000 * (1/4)

In a bag of plain M&M's, the Masterfoods company states that yellow and red candies each make up 20% of the total, while orange, blue, and green each make up 10%. T

(a) The probability that a randomly picked M&M is brown is determined by the fraction of brown candies in the bag. Since all other colors account for 60% (20% + 20% + 10% + 10% + 10%), the probability of picking a brown M&M is 1 - 0.60 = 0.40, or 40%.

(b) To calculate the probability of picking a yellow or green M&M, we sum the individual probabilities of each color. The probability of picking a yellow M&M is 20%, and the probability of picking a green M&M is 10%. Adding these probabilities, we get 20% + 10% = 30%, or 30% chance of picking a yellow or green M&M.

(c) The probability of not picking a green M&M is the complement of the probability of picking a green M&M. Since the probability of picking a green M&M is 10%, the probability of not picking a green M&M is 1 - 0.10 = 0.90, or 90%.

(d) The information provided does not specify the proportion of striped M&M's in the bag. Without this information, we cannot determine the probability of picking a striped M&M.

In summary, the probability of picking a brown M&M is 40%, the probability of picking a yellow or green M&M is 30%, the probability of not picking a green M&M is 90%, and the probability of picking a striped M&M cannot be determined with the given information.
