Mi is about to roll a six-sided number cube. What is the experimental probability that she will roll an even number based on her

Kryger [21]

Answer: The experimental probability that she will roll an even number= $\frac{1}{2}$

Step-by-step explanation:

We know that the probability for any event is given by6;-

$\text{Probability}=\frac{\text{Favorable outcomes}}{\text{Total outcomes}}$

In a dice, the total even numbers (2,4,6)= 3

Therefore, the probability that she will roll an even number will be given by:-

$\text{Probability}=\frac{\text{3}}{\text{6}}=\frac{1}{2}$

Hence, The experimental probability that she will roll an even number= $\frac{1}{2}$

The standard deviation of a normally distributed population is 24.0. A sample of size 4 is randomly selected. The standard error

Vlad1618 [11]

The standard error of the mean is 12.

The standard error of the mean points to the standard deviation of the distribution of a sample mean obtained from a population.

The standard error S.E of the mean can be calculated by using the formula:

$\mathbf{S.E = \dfrac{\sigma }{\sqrt{n}}}$

where;

standard deviation $\sigma$ = 24
sample size n = 4

$\mathbf{S.E = \dfrac{24 }{\sqrt{4}}}$

$\mathbf{S.E = \dfrac{24 }{2}}$

S.E = 12
