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]
<u></u>

Answer: $108.75
Step-by-step explanation: 18.50+3.25=21.75 Per Person 21.75x5=108.75
The perimeter is 2 width + 2 length. So 200 = 2(36) + 2 length and that simplies to 200 = 72 + 2 length. Now we have to subtract 72 from both sides to get the 2 lengths alone. So 128 = 2 length. Finally, we divide both sides by 2 to get the length alone. 64 = length. Now since the perimeter has to be less than 200 inches than the length can be any number less than 64. Hope this helps and if so please leave a good rating and thanks and maybe even brainliest answer. Thank you I really appreciate it. Have a nice day!
