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

2/3 divided by 1/4<br> HELP ME PLEASEEE
kap26 [50]

Answer: 2 and 2/3

Step-by-step explanation: In this problem, we have 2/3 ÷ 1/4.

Dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the divison sign to multiplication and flip the second fraction.

So here, 2/3 ÷ 1/4 can be rewritten as 2/3 × 4/1.

Now we are simply multiplying fractions so we multiply across the numerators or top number number and multiply across the denominators or bottom numbers.

\frac{2}{3} x \frac{4}{1} = \frac{8}{3}  

8/3 can be converted into a mixed number by dividing the denominator of the fraction into the numerator of the fraction.

3 divides into 8 2 with a remainder of 2 times so our whole number will be 2 and our new numerator will be 2 as well. We will put this over our original denominator which is 3. Now we have 2 and 2/3.
