Answer:
116
Step-by-step explanation:
8.2 / 2 = 4.1
a = 
0.5 x 8.2 x 5.6736 = 23.2618
23.2618 x 5 = 116.309 = 116
 
        
             
        
        
        
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>
  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] 
<u></u>
