Sauron [17]

Answer: 1/4 or 0.25

Step-by-step explanation: We will solve log256 4 in several steps to solve for x.

Step 1: Log256 4 = x

Step 2: 256x = 4 ( Next, Use exponents )

Step 3: (2^8)x = 2^2

Step 4: 2^8x = 2^2

Step 5: 8x = 2 (Solve for x0

Step 6: 8x/8 = 2/8 = x = 1/4

Step 7 (The Answer) x, or log256 4 = 1/4 or 0.25

population mean =72 and standard deviation =10, what is standard error of distribution of sample means for n=4 and n=25

mixer [17]

Answer:

The standard error of distribution for n = 4 is 5 and for n = 25 is 2.

Step-by-step explanation:

1. Let's review the information given to us for solving the question:

Population mean = 72

Standard deviation = 10

Sample₁ = 4

Sample₂ = 25

2. For finding the standard error of the mean, we use the following formula:

Standard error = Standard deviation / √Size of the sample

Standard error for Sample₁ = 10/√4

Standard error for Sample₁ = 10/2 = 5

Now, let's find the standard error for Sample₂

Standard error for Sample₂ = 10/√25

Standard error for Sample₂ = 10/5 = 2
