A doctor is interested in people who have experienced an unexplained episode of vitamin D intoxication. She took a SRS of size 1

Mila [183]

Answer:

(a) (2.573, 3.167) is the 99% confidence interval for $\mu$ the true mean calcium level of the population of people who experienced an unexplained episode of vitamin D intoxication.

(b) There is a 99% probability that the average calcium level of all people who have experienced an unexplained episode of vitamin D intoxication is in the interval.

Step-by-step explanation:

If we have a random sample of size n from a normal distribution with mean $\mu$ and standard deviation $\sigma$ , then we know that $\bar{X}$ is normally distributed with mean $\mu$ and standard deviation $\sigma/n$ . Therefore we can use $(\bar{X}-\mu)/\frac{\sigma}{\sqrt{n}}$ as a pivotal quantity.

We have a sample size of n = 12. The sample mean is $\bar{x}$ = 2.87 mmol/l and the standard deviation is $\sigma = 0.40$ . The confidence interval is given by $\bar{x}\pm z_{\alpha/2}(\frac{\sigma}{\sqrt{n}})$ where $z_{\alpha/2}$ is the $\alpha/2$ th quantile of the standard normal distribution. As we want the 99% confidence interval, we have that $\alpha = 0.01$ and the confidence interval is $2.87\pm z_{0.005}(\frac{0.40}{\sqrt{12}})$ where $z_{0.005}$ is the 0.5th quantile of the standard normal distribution, i.e., $z_{0.005} = -2.5758$ . Then, we have $2.87\pm (-2.5758)(\frac{0.40}{\sqrt{12}})$ and the 99% confidence interval is given by (2.573, 3.167)

(b) We found a 99% confidence interval for the true mean calcium level of the population of people who experienced an unexplained episode of vitamin D intoxication. Therefore, there is a 99% probability that the average calcium level of all people who have experienced an unexplained episode of vitamin D intoxication is in the interval.

$\Huge\boxed{V=550}$

Step-by-step explanation:

Hello There!

For this problem we want to split the irregular 3d figure into two regular 3d figures

Two rectangular prisms with the following dimensions

rectangular prism 1

length - 5 feet

width - 12 feet

height - 5 feet

rectangular prism 2

length - 5 feet

width - 5 feet

height - 10 feet (was found by subtract height of rectangular prism 1 (5 feet) from the total height of the irregular figure (15-5=10 so the height of rectangular prism 2 is 10 feet)

Now to find the volume of each individual prism...

So remember the formula for volume of a rectangular prism is

volume = length x width x height

so having the dimensions of each rectangular prism we plug in each value to the formula ( remember we're doing this for each individual rectangular prism)

For rectangular prism 1

V = 12 x 5 x 5

12x5x5=300 so the volume of rectangular prism is 300 cubic feet

For rectangular prism 2

V = 10 x 5 x 5

10x5x5=250 so the volume of rectangular prism is 250 cubic feet

our final step is to add the two volumes together

250 + 300 = 550

so we can conclude that the volume of the rooftop is 550

1. What is the value of x in the equation –6 + x = –2?

IgorC [24]

1. A. Add 6 to both sides to solve.

2. D. If you simplify the a terms you will get 6 = 7 which is never true.

3. A. Subtract 1.2m from both sides and then divide to solve.

4. B. If you simplify you get 7 = 7 which is always true.

5. D. Distribute the 2 and then add the 24 to both sides. Then divide to solve.

6. A. Simplify the right side and then divide all by two. Then add 16 to both sides and divide by 4.

The library is 3.56 kilometers from Maria's house and 1.38 kilometers from Simon's house. How much farther does Maria live from

arlik [135]

Answer: 2.18 kilometres

Step-by-step explanation:

First we take down the information given to us

Maria's house to library (distance) = 3.56 km

Simon's house to library (distance) = 1.38 km

Now to get how farther Maria lived from the library compared to Simon, we subtract the distance between the library and Simon's house from the distance between the library and Maria's house

i.e

3.46km - 1.38km = 2.18km

there for Maria lived 2.18 kilometres farther from the library compared to Simon.
