g True or False: A sample of size 25 provides a sample variance of 400. The standard error in this case, equal to 4, is best des

Tpy6a [65]

Answer:

True.

Step-by-step explanation:

If we have for a sample of size n=25 a sample variance of 400, the standard error can be written as:

$\sigma_s=\dfrac{\sigma}{\sqrt{n}}=\dfrac{\sqrt{400}}{\sqrt{25}}=\dfrac{20}{5}=4$

This way of calculating the standard error is the same used for estimating the standard deviation of the sample means for samples of size n=25.

What is 7/10+20/100?

Firdavs [7]

9/10. make the bottom numbers the same to add fractions. you can do that by multiplying 7/10 by 10/10.

70/100 + 20/100 = 90/100

90/100 = 9/10

you can also reduce 20/100 to 2/10.

7/10 + 2/10 = 9/10

The perimeter of a rectangle is 34 units. Its width is 6.5 units. Write an equation to determine the length of the rectangle.

julsineya [31]

Answer:

The length for a rectangle with a perimeter of 34 units and a width of 6.5 units would be 10.5 units.

Step-by-step explanation:

To find the length, you can use the equation [34 - (6.5 x 2) ÷ 2 = the length]. So, 6.5 x 2 = 13, then 34 - 13 = 21, finally, 21 ÷ 2 = 10.5 . So the length of the rectangle is 10.5 . To double check, (6.5 x 2) + (10.5 x 2) (=) 34. So this answer is correct.

Answer:

0.8809

Step-by-step explanation:

Given that:

The population proportion p = 4% = 4/100 = 0.04

Sample mean x = 16

The sample size n = 300

The sample proportion $\hat p =\dfrac{x}{n}$
