We are given equation c=50p.
c is the total cost and p is the number of people.
Let us take number of people by groups of 10, 20, 30,40 people.
Note: We can take any positive integer for number of people in a group.
Now, we need to plug p=10, 20, 30,40 one by one in given function c=50p to find the costs c.
Plugging p=10, we get
c= 50*10 = 500.
Plugging p=20, we get
c= 50*20 = 1000.
Plugging p=30, we get
c= 50*30 = 1500.
Plugging p=40, we get
c= 50*40 = 2000.
So, we can create a table as.
Number of people (p) Total cost (c)

10 500
20 1000
30 1500
40 2000
It is given in the question that
Ben has a collection of 812 stamps. He gives his brother 345 stamps.
And we have to find how many stamps does Ben have left .
Let x stamps are left.
So we have
Subtracting 345 from both sides
Therefore after giving 345 stamps to his brother, 467 stamps are left .

Using it's definitions, the five-number summary and the interquartile range for the data-set is given as follows:
<h3>What are the median and the quartiles of a data-set?</h3>
- The median of the data-set separates the bottom half from the upper half, that is, it is the 50th percentile.
- The first quartile is the median of the first half of the data-set.
- The third quartile is the median of the second half of the data-set.
- The interquartile range is the difference of the third quartile and the first quartile.
This data-set has 12 elements, which is an even number, hence the median is the mean of the 6th and 7th elements, as follows:
Me = (19 + 23)/2 = 21.
The first quartile is the median of 6, 7, 8, 8, 16, which is the third element of 8.
The third quartile is the median of 23, 24, 26, 27, 34, 35, which is of 27. Hence the interquartile range is of 27 - 8 = 19.
The minimum is the lowest value in the data-set, which is of 6, while the maximum is of 35, which is the largest value in the data-set.

Solution :
a). The required linear regression model is
Price = 
b). The 
for the variable "Age of part" is 0.0000
Since the is less than 0.05, so it is significant to the model.
The p-value for the variable "Number of bidders" is 0.1940
Since is not less than 
, so it is significant to the model.
c). We cannot say that model is significant because variable " the number of bidders" is not significant.
But as both variables have positive coefficient so as the variable increases the price received for the item also increased.
