When using scientific notation, you only want one number to be in front of the decimal place. If you have to make the number smaller, then the 10^nth power will be positive. If you have to make the number bigger, then 10^nth power will be negative. Example:
0.54 --> 5.4 * 10^-1
35 --> 3.5 * 10^1
The value of n depends on how many spaces the decimal point needs to be moved. For your question, putting 23 in scientific notation would look like this:
23 --> 2.3 * 10^1

A population of values his normal distribution with men equal to 27.6 and standard deviation equal 39.4 do you intend to draw a
Alecsey [184]

Answer:

The mean of the distribution of sample means is 27.6        

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 27.6

Standard Deviation, σ = 39.4

We are given that the population is a bell shaped distribution that is a normal distribution.

Sample size, n = 173.

We have to find the mean of the distribution of sample means.

Central Limit theorem:

  • It states that the distribution of the sample means approximate the normal distribution as the sample size increases.
  • The mean of all samples from the same population will be approximately equal to the mean of the population.

Thus, we can write:

\mu_{\bar{x}} = \mu = 27.6

Thus, the mean of the distribution of sample means is 27.6

sveta [45]

Answer:

log(32/125)

=log32 - log125 [log(x/y)=log(x) - log(y)]

=log(2)^2 - log(5)^3

=2log2-3log5 [log(x)^p=p log x]

=2a-3b
