11 years 11 months

[Lack of spacing in the above problem hindered the word wrap algorithm. A raw view of this page shows that the 5th child is actually 10years11months.]

There are many reasons a young child may struggle with day to day routines. The most common reason is their attention span. Up to the age of 5 years old, a child usually has one minute of attention span per age, so a 2 year old has a two minute attention span, a 4 year old has a 4 minute attention span, and so on and so forth.

The second most common reason is that they are given too much responsibility too soon. While children can help with chores at all ages, the chores need to be age appropriate, so you might give a 2 year old a dust rag to wipe a table with but you wouldn't give them a vacuum cleaner of course.

Another common reason is that children don't get nearly enough sound sleep these days. Infants and toddlers need on average 12-14 hours of sleep a night. Some may be able to get away with as few as 10 hours, and others may need as many as 16 hours of sleep a night. 3-5 year old's need anywhere from 10-13 hours of sleep a night and some need as many as 14 hours of sleep a night, while others can survive on only 9 hours of sleep a night. Older children in the 6-13 range need a minimum of 9 hours a sleep a night, and the average child in that range needs 10-11 hours of sleep. Some get by on as few as 7 hours while others need as many as 12 hours. No child under the age of 13 should be sleeping less than 9 hours a night. If they are, it could be one of the reasons that you struggle with the day to day routine, especially if it's the morning routine.

Other common reasons for a child having a hard time with a day to day routine is the need for a nap, not drinking enough water, too long of a wait between meals or snacks that's causing low blood pressure, and distractions by siblings, video games, etc.

ring the venue and ask that question

it will depend on the age and the venues policy for children

I could give you the answer but this website explains very nicely, how to calculate each type of average. The second example they use fits your list of numbers better than the first.

There are an infinite number of solutions. One solution is {7, 8, 8, 8, 9}.

The question is incomplete.

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

**To find the median: **

Data values 12.5, 13, 13., 13,**13.5**, 14, 19.5, 19.5, 20

**Mean** =(12.5+13+13+13+13.5 +14+19.5+19.5+20)/9=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

**Median**=13.5

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

**Mean** =(12.5+13+13+13+**13.5** +**14**+19.5+19.5+20 + 25)/10=?

**Mode**= most frequent value. Here it is 13 (repeated 3 times)

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

**Value of Median** =(13.5+14)/2=?

The mean, also called the average is defined as

mean= (sum of the data values)/(number of data elements)

Mode = the most frequent data value (the one that is most repeated)

- Order the data values in ascending order (sort them from the smallestr to the largest), and
- Locate the data value that is in the middle.
- If the number of data values id ODD (not a multiple of 2) there is only one middle element. That is the median.
- If the number of data elements is EVEN (multiple of 2), there is not one middle element but two.
- The median is the average of the two middle element values
**Median =( left of middle value +right of middle value)/2****Imagine this median value to be inserted between the two middle elements**

Data values 12.5, 13, 13., 13,

There are 9 values, an odd number. Middle element is the 5th ( 13.5)

Example 2

Data values 12.5, 13, 13., 13, 13.5, 14, 19.5, 19.5, 20, 25

There are 10 values, an even number. Middle element is not among the values. There are two middle elements (the 5th and the 6th) or

The value of the median is the average of the 5th and 6th elements or

mean: 77

median: 87

mode: none or all of them (take your choice)

range: 43

If this is homework, be sure to show your work.
