Answer:
<h2>The slope m = -2</h2>Step-by-step explanation:
The slope-intercept form of an equation of a line:
<em>m</em><em> - slope</em>
<em>b</em><em> - y-intercept</em>
<em />
We have the equation in the standard form:
Convert to the slope intercept form:
<em>subtract 6x from both sides</em>
<em>divide both sides by 3</em>
slope: <em>m = -2</em>
y-intercept: <em>b = 4</em>
Answer:
a

b
c
Step-by-step explanation:
From the question we are are told that
The sample data is 21, 14, 13, 24, 17, 22, 25, 12
The sample size is n = 8
Generally the ample mean is evaluated as
Generally the standard deviation is mathematically evaluated as
considering part b
Given that the confidence level is 90% then the significance level is evaluated as
Next we obtain the critical value of from the normal distribution table the value is
The margin of error is mathematically represented as
=>
=>
The 90% confidence interval is evaluated as
substituting values
considering part c
Given that the confidence level is 95% then the significance level is evaluated as
Next we obtain the critical value of from the normal distribution table the value is
The margin of error is mathematically represented as
=>
=>
The 95% confidence interval is evaluated as
substituting values
