Julli [10]

Answer:

The standard error of the mean is 0.0783.

Step-by-step explanation:

The Central Limit Theorem helps us find the standard error of the mean:

The Central Limit Theorem estabilishes that, for a random variable X, with mean \mu and standard deviation \sigma, a large sample size can be approximated to a normal distribution with mean \mu and standard deviation \frac{\sigma}{\sqrt{n}}.

The standard deviation of the sample is the same as the standard error of the mean. So

SE_{M} = \frac{\sigma}{\sqrt{n}}

In this problem, we have that:

\sigma = 0.35, n = 20

So

SE_{M} = \frac{\sigma}{\sqrt{n}}

SE_{M} = \frac{0.35}{\sqrt{20}}

SE_{M} = 0.0783

The standard error of the mean is 0.0783.

dolphi86 [110]

Answer:

66045 ways

Step-by-step explanation: There are actually total of 37 student, and total of 4 jobs. But if the jobs are to be done by only one person each, then we are selecting 4 students.

So the number of ways of selecting 4 out of 37 using combination is

=37C4

=37!/(37-4)!(4!)

=37!/33!4!

=66045
