Here you find the largest factor shared by the two numbers : 72 and 78. This is the same as finding the G.C.F of a set of numbers.In finding the greatest common factor, list the prime factor of each number and multiply the factors that both numbers have in common. In this case, it will be:

72 78 --------------divided by 2

2 36 39 --------------divided by 3

3 12 13 --------------no common divider

The greatest number of orange beads and blue beads bracelets will be 2*3=6

If all the possible random samples with n = 36 scores are selected from a normal population with µ = 50 and σ = 18, and the mean

ozzi

Answer:

Expected Value of M is 50 and the Standard Error of M is 3

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean $\mu$ and standard deviation $\sigma$ , the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean $\mu$ and standard deviation, also called standard error $s = \frac{\sigma}{\sqrt{n}}$ .

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

µ = 50 and σ = 18

For the sample

Mean 50 and standard error $s = \frac{18}{\sqrt{36}} = 3$ .

The answer is:

Expected Value of M is 50 and the Standard Error of M is 3
