Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 10, 1, 10, 15, 1, 7, 10, 10, 1, 6
klemol [59]
First order the data:
1, 1, 1, 6, 7, 10, 10, 10, 10, 13, 15
the mean is all the numbers added together divided by how many there are, 1 + 1 + 1 + 6 + 7 + 10 + 10 + 10 + 10 + 13 + 15 = 84 84/11 = 7.636364 ≈ 7.6
the median is the number in the middle of the list, count numbers from each end, until you either have one or two left, if one left then its that one, if two left then its half way between the two
the median for your set is 10
The mode is the most common number, in your set 10
Answer:
bottom right, x = 90
bottom left, x = 40
top left, x = 28
Step-by-step explanation:
This problem uses the variable x to mean three different numbers.
This is an incorrect use of a variable.
On the bottom right, x is a right angle, so x = 90.
On the bottom left, x + 5 = 45, so x = 40.
On the top left, 3x + 6 = 90, so x = 28.
Most likely in millilitres, kilolitres is too large for a small cup, and the other measurements are for mass
Answer:
Will have an expected value of the mean = 80 and a standard error of the mean = 5
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean 
and standard deviation 
, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean and standard deviation 
.
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:
n = 16
So the mean is 80 and the standard deviation is 
Will have an expected value of the mean = 80 and a standard error of the mean = 5
