After arriving at the university student medical clinic, the waiting times to receive service after checking-in follow an expone

Marina CMI [18]

Answer:

6 students are served per hour.

45.12% probability a student waits less than 6 minutes.

Step-by-step explanation:

Exponential distribution:

The exponential probability distribution, with mean m, is described by the following equation:

$f(x) = \mu e^{-\mu x}$

In which $\mu = \frac{1}{m}$ is the decay parameter.

The probability that x is lower or equal to a is given by:

$P(X \leq x) = \int\limits^a_0 {f(x)} \, dx$

Which has the following solution:

$P(X \leq x) = 1 - e^{-\mu x}$

mean of 10 minutes.

This means that $m = 10$ , so $\mu = \frac{1}{10} = 0.1$

How many students are served per hour?

One student is served each 10 minutes, on average

An hour has 60 minutes

60/10 = 6

6 students are served per hour.

Calculate the probability a student waits less than 6 minutes.

$P(X \leq x) = 1 - e^{-0.1*6} = 0.4512$

45.12% probability a student waits less than 6 minutes.

Ten subjects are being studied to test the effectiveness of itch relief for three types of medication: A, B, and C. Using a 10-p

yan [13]

Answer: Choice C

They should be blocked by pain resistance so the subjects are as similar as possible.

============================================================

Explanation:

The process of blocking in statistics is where we group up people in blocks, and each block is determined by a characteristic of some sort. In this case, we're grouping people up by pain resistance level. Those very resistant to pain will be in one group, while those who easily feel pain will be in another block, and so on. It might be effective to have a pain scale and sort people by that.

Blocking is done so that we eliminate unwanted variability. We are testing the effectiveness of the itching cream, so all we care about is if the itch reduces or not. We aren't worried about the levels of pain. However, it says that "Previous studies have shown the effects of treatment may vary based on a subject's pain resistance". So we group up the people by pain tolerance to help eliminate the variability of pain tolerance levels.

This is why choice C is the final answer.

-------------

Extra info:

Choice A is false because a person's name doesn't have anything to do with if the treatment works or not.
Choice B is false because we weren't given any info to indicate it being true. It may be true, but we simply don't have enough info to confirm it.
Choice C is false for similar reasons as choice B.

Evaluate (x + y)0 for x = -3 and y = 5. A. -1/2 B. 0 C. 1 D. 2

Anastasy [175]

Hello there! With the values of "x" and "y", they fill in the parenthesis. -3 + 5 is 2, because adding into a negative makes the number go up, or just simply subtracting 3 from 5 works as well. However, there is a 0 beside it, so we raise 2 to the 0 power. Anything that is raised to the 0 power is always equal to 1. And there is no other part of the question, so 1 is our answer. The answer is C: 1.
