Answer:
b) 95 percent confidence interval for this single-sample t test
[11.64, 16.36]
Step-by-step explanation:
Explanation:-
Given data a study of 62 college students finds that their average interest rate is 14 percent with a standard deviation of 9.3 percent.
Sample size 'n' =62
sample mean x⁻ = 14
sample standard deviation 'S' = 9.3
<u>95 percent confidence interval for this single-sample t test</u>
The values are the <u>95 percent confidence interval for the population mean 'μ'</u>
Degrees of freedom γ=n-1=62-1=61
t₀.₀₅ = 1.9996 at 61 degrees of freedom
(14-2.361 , 14 + 2.361)
[(11.64 , 16.36]
<u>Conclusion:-</u>
95 percent confidence interval for this single-sample t test
[11.64, 16.36]

The answer has to resemble y=Mx+b so to find your y intercept plug in your coordinates into that equation so put your slope in for m and your x intercept in for x and the y intercept in for y so -4= -3(-1)+b now get b alone -1=b so your equation would be y=-3x-1
7 copies I assume means multiplication. 7 x 1/4=7/4. When multiplying fractions, the numerator is multiplied.
Given function is
Now question says to find the graph that shows the axis of symmetry for the given function.
Graph is missing but I can help you to find the correct graph.
Given equation is in the vertex form whose formula is given by
Comparing given function with above formula, we get:
a=1, h=2 and k=1.
For the vertex formula , we know that axis of symetry is given by equation:
x=h
So for the given function, axis of symmetry will be x=2
Graph of x=2 will be a vertical line crossing x-axis at x=2
So you just need to find the graph from given choices which contains a vertical line crossing x-axis at x=2.
