In a population, 11% of people are left handed. In a simple random sample of 160 people selected from this population, the propo

Answer:

The claimed proportion (population) is

$p=0.11$

The sample proportion (p-hat) is

$\hat{p}=0.10$

Step-by-step explanation:

In the population, we have the parameter p that is 11%.

$p=0.11$

Then, a sample of n=160 is taken and the proportion of the sample is 0.10.

$\hat{p}=0.10$

The sample proportion p-hat can differ from the population's proportion. There is a sampling distribution that gives the possible values of the sample proportion taken out of this population and its associated probabilities.

Find the greatest common factor for pair 18,36

netineya [11]

The GCF of 18 and 36 is 18. To solve this, use the picture attached. After creating the boxes, find a number that both 18 and 36 can be divided by, for example, 9. Now that you have 9, divide both 18 and 36 by 9. That equals 2 and 4. Place the numbers underneath the boxes you made previously and find another number that both 2 and 4 are divisible by. 2 and 4 are both able to be divided into 2. Do 2 divided by 2 and 4 divided by 2. Now you have the numbers 1 and 2. There aren't any numbers that can be divided into 1 and 2, so now you are left with the numbers 9 and 2. Multiply the numbers together to get a GCF of 18. Hope this helped!
