A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model

Nana76 [90]

Answer:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be ∅ $/\sqrt{n}$

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅ $/\sqrt{n}$ 1

c. As the size of the sample increases, the sample distribution should draw near and resemble the distribution of the population

Step-by-step explanation:

A sample is chosen randomly from a population that was strongly skewed to the left. a) Describe the sampling distribution model for the sample mean if the sample size is small. b) If we make the sample larger, what happens to the sampling distribution model’s shape, center, and spread? c) As we make the sample larger, what happens to the expected distribution of the data in the sample?

The following answers will march the questions above:

a. The sampling distribution for the sample mean will be skewed to the left centered at the average u, and standard deviation will be ∅ $/\sqrt{n}$

b. The sample distribution will be normal in shape and will be centered at the average u, . standard deviation will be ∅ $/\sqrt{n}$ 1

c. As the size of the sample increases, the sample distribution should draw near and resemble the distribution of the population

Answer:

on flipping a coin, we either get a heads or a tails and both the events are equally likely. So the probablity of getting a tails is 1/2.

Now

On rolling a die, we can get 6 possible outcomes(1,2,3,4,5,6)

But the favourable outcomes (an even number) are only 3. So the probablity of getting an even number is 3/6=1/2

In case. we have 2 events that need to occur together, we simply need to multiply their individual probablities to get the probablity of getting both the events together

So our required answer is

p(even number)× p(tails)= 1/2 × 1/2 = 1/4
