Answer: 95% confidence interval would be (26.01,29.39).
Step-by-step explanation:
Since we have given that
n = 50
Mean = 27.7
Standard deviation = 6.12
We need to construct 95% confidence interval for the population.
so, z = 1.96
So, it becomes,

Hence, 95% confidence interval would be (26.01,29.39).
All of the above is the correct answer
Answer:
The answer is:O f(1) = 10, f(n) = f(n − 1) + 2, for n > 1
Step-by-step explanation:
f1=10 because the first number is 10. then f(n)=f(n-1)+2 for N because it goes up 2 every time.
