Answer and Step-by-step explanation: Scaterplot is a type of graphic which shows the relationship between to variables. In this question, you want to determine if there is a linear relationship between overhead widths of seals and the weights. So, the hypothesis are:
H₀: no linear correlation;
H₁: there is linear correlation;
In this hypothesis test, to reject H₀, the correlation coefficient r of the data set has to be bigger than the critical value from the table.
With α = 0.05 and n = 6, the critical value is 0.811.
The linear correlation is calculated as:
r = n∑xy - ∑x.∑y / √[n∑x² - (∑x)²] [n∑y² - (∑y)²]
r =
r = 0.9485
Since r is bigger than the critical value, H₀ is rejected, which means there is enough evidence to conclude that there is linear correlation between overhead widths and the weights.
In the attachments is the scaterplot of the measurements, also showing the relationship.

Step-by-step explanation:
we have
<em>Find the x-intercept</em>
Remember that the x-intercept is the value of x when the value of y is equal to zero
For y=0
the x-intercept is the point (2,0)
<em>Find the y-intercept</em>
Remember that the y-intercept is the value of y when the value of x is equal to zero
For x=0
the y-intercept is the point (0,-5)
using a graphing tool
Plot the intercepts and connect them to graph the line
