The mean and standard deviation of a population being sampled are 64 and 6, respectively. If the sample size is 50, what is the standard error of the mean? how do I find the standard error?

Answers

Answer 1

Answer: SEM - Standard error of the mean;
You can find the standard error with a formula:
SEM = s / √n, where s is the standard deviation and n is the sample size;
SEM = 6 / √50 = 6 / 7.071
Answer:
SEM = 0.8485

Answer 2

Answer:

Final answer:

The standard error is calculated as the standard deviation divided by the square root of the sample size. For a population with a standard deviation of 6 and a sample size of 50, the standard error is 6 / sqrt(50).

Explanation:

The standard error can be defined as the standard deviation divided by the square root of the number of samples. It helps to estimate the variability in the population. In this case, the mean is 64, the standard deviation is 6, and the sample size is 50. The equation to calculate the standard error is:

$Standard Error = Standard Deviation / \sqrt(Sample Size).$

Plugging in the values given in the question, we get:

$Standard Error = 6 / \sqrt(50)$

. After performing the division, you will get the standard error of the mean which tells you how far your sample mean could be from the true population mean.

Original price is 45.00 and the markup is 57%

Answers

57 percent of 45 is 25.65.

45 + 25.65 = 70.65

Final price with markup is $70.65

$70.65 cuz 57% of 45 is $25.65 and when u add the $45, since it's a markUP not a markdown you get $70.65

Answers

Answer:

Step-by-step explanation:

Answer:

Step-by-step explanation:

700 divided by 12 is 58.3 repeating. You can't spell a fraction of a cap, therefore you must sell 59. This meets the goal of at least 700 caps sold in total.

1st step because 2 times x is 2x and 2 times 3 is 6

Answer:

Step 1

Step-by-step explanation:

2(x + 3) = 8

1. 2x + 6 = 8

2. 2x = 2

3. x = 1

In step 1, she distributed the 2 to the x and 3 by multiplying them and getting 2x and 6.
