There are 20 children at a library. Six of the children have an average age of 5 years. The remaining children have an average a

Allushta [10]

Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years
14 x 8 = 112 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

A recent report in a women magazine stated that the average age for women to marry in the United States is now 25 years of age,

MrRissso [65]

Answer: 0.0136

Step-by-step explanation:

Given : Mean : $\mu=\ 25$

Standard deviation : $\sigma= 3.2$

Sample size : $n=50$

The formula to calculate the z-score :-

$z=\dfrac{x-\mu}{\dfrac{\sigma}{\sqrt{n}}}$

For x = 24

$z=\dfrac{24-25}{\dfrac{3.2}{\sqrt{50}}}=-2.20970869121\aprox-2.21$

The P-value = $P(z\leq24)=0.0135526\approx0.0136$

Hence, the probability that the sample mean age for 50 randomly selected women to marry is at most 24 years = 0.0136
