f a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the st

galina1969 [7]

This question is incomplete, the complete question is;

A study on the latest fad diet claimed that the amounts of weight lost by all people on this diet had a mean of 24.6 pounds and a standard deviation of 8.0 pounds.

Step 2 of 2 : If a sampling distribution is created using samples of the amounts of weight lost by 51 people on this diet, what would be the standard deviation of the sampling distribution of sample means? Round to two decimal places, if necessary.

Answer:

the standard deviation of the sampling distribution of sample means is 1.12

Step-by-step explanation:

Given the data in the question,

population mean; μ = 24.6 pounds

Population standard deviation; σ = 8.0 pounds

sample size; n = 51

Now determine the standard deviation of the sampling distribution of sample means.

standard deviation of the sampling distribution of sample means is simply

⇒ population standard deviation / √sample size

= 8.0 / √51

= 8.0 / 7.141428

= 1.120224 ≈ 1.12

Therefore, the standard deviation of the sampling distribution of sample means is 1.12

Which of the following represents the sum of the series? 6 8 10 12 14 16 18 20 22 24 26

stira [4]

The sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176

<h3>How to determine the sum of the series?</h3>

The series is given as:

6 8 10 12 14 16 18 20 22 24 26

The above series is an arithmetic series with the following parameters:

First term, a = 6

Last term, L = 26

Number of terms, n = 11

The sum of the series is calculated using:

$S_n= \frac{n}{2} *(a + L)$

This gives

$S_n= \frac{11}{2} *(6 + 26)$

Evaluate

$S_{11} = 176$

Hence, the sum of the arithmetic series 6 8 10 12 14 16 18 20 22 24 26 is 176

Which number is the farthest from - 2 on the number line?<br><br>A. 6<br>B. 0<br>C. -1<br>D. -9

Leya [2.2K]

Answer: A. 6

Step-by-step explanation: if you go from -2 to 6 you go 8 spaces. You go from -2 to 0 which is 2 spaces, and they 6 more spaces to get to 6. If you went to -9 you are going 7 spaces. and to 0 you go 2 spaces, and -1 you go one space. So, the furthest is positive 6.

Hope this helps ^_^
