Answer: -0.64
Step-by-step explanation:
We know that the coefficient of determination in a simple linear regression model is denoted by , which gives the proportion of the variance in the dependent variable that is predictable from the independent variable.
Given, the coefficient of determination in a simple linear regression model is 64%.
i.e.
As there is negative relation between the dependent and independent variables.
Then, the correlation coefficient = -0.64
Answer:
<h3>Option A) Estimates a likely interval for a population mean is correct</h3><h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3>Step-by-step explanation:
Given that a confidence interval for a population mean <u>Estimates a likely interval for a population mean</u>
For :
A confidence interval is a range of values that’s likely to include a population value with a certain degree of confidence.
It can be expressed as a the (percentage value) where by a population mean lies between an upper and lower interval.
Therefore a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u>
Option A) Estimates a likely interval for a population mean is correct
<h3>Hence a confidence interval for a population mean is used to <u>Estimates a likely interval for a population mean</u></h3><em>Question Continuation:</em>
<em>Glenn bought 3 pounds of tomatoes. He used 5/8 of them to make sauce. </em>
<em>Make an equation that shows the number of pounds of tomatoes Glenn used for the sauce.</em>
<em></em>
Answer:
Step-by-step explanation:
Given
Weight of Tomato = 3 lb
Used Proportion = 5/8
Required
Determine the portion used
To solve this we simply multiply the used proportion by the weight of the tomato bought
Represent the used portion with y.
So:
