Answer:
(a) The amount of ice cream increase as temperature increases
(b)
--- equation
--- y intercept
--- slope
Step-by-step explanation:
Given
See attachment for graph
Solving (a): The relationship between the variables
From the attached graph, the dots on the graph increases towards up-right direction. This implies that there is a positive correlation between the variables.
In other words;
The amount of ice cream increase as temperature increases
Solving (b): The line of best fit
First, we draw a line through the points (the line should have almost equal points on both sides; see attachment 2).
From (2), we select any 2 points on the line:
The slope (m) is:
So, the line of best fit is:
Substitute known values:
The y-intercept is when
So, we have:
The solution for this problem is:
The x-bar or the mean is = 150Confidence level is 80%sample size is 36
E = t*s/sqrt(n)= 1.3062*40/sqrt(36)=1.3062 * 6.66667= 8.708
An 80% Confidence Interval is: 150-8.708 < u < 150+8.708Or141.3 < u < 158.7 is the confidence interval
Answer:
1 hour rate = 180 - 5 hour rate = 900
Step-by-step explanation:
To make the whole equation easy divide the number of people by the time.
75 / 25 = 3
Now the number of people can be adjusted to any amount of time.
For the hour rate multiply the number of people per minute by 60.
3 x 60 = 180
For the five hour rate use the same exact equation but multiply the 60 by 5 first.
3 ( 60 x 5 ) = 900
Hope this helped.
