Answer:

Mean- Average
Median- the middle number in a sorted, ascending or descending
Mode- the most commonly observed value in a set of data

Using the example of- 1, 2, 2, 3, 3, 3, 4, 5, 6, 7

Mean- Average, (the sum of every value)/10(# of values)= 3.2

Median- 3 (even though there are 2 3s, but add them up and divide the sum by 2)

Mode- 3

3. Well... you could use these data to do science reports etc, ofc in the world of academics, you would need to use this kind of statistics terms a lot. In normal life, you might have to compare the price of similar products and see which is the best to purchase, seeing the value of the median of the entire set of data.

If the distribution is really N ( 5.43 , 0.54 ) , N(5.43,0.54), what proportion of observations would be less than 5.05 ? 5.05?

Ipatiy [6.2K]

Answer:

$P(X$

And we can use the following excel code to find the answer: "=NORM.DIST(-0.704,0,1,TRUE)"

Step-by-step explanation:

Previous concepts

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

The Z-score is "a numerical measurement used in statistics of a value's relationship to the mean (average) of a group of values, measured in terms of standard deviations from the mean".

Solution to the problem

Let X the random variable of interest for a population, and for this case we know the distribution for X is given by:

$X \sim N(5.43,0.54)$
