Answer: c. 
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where n= sample size
= sample mean.
z*= Critical value.
= population standard deviation.
As per given , we have
n= 50
Also, we know that the critical value for 95% confidence interval : z*= 1.96
Then, the 95% confidence interval (CI) to estimate the true average score of golfers on this particular course will be :
(substitute all the value in the above formula.)
Hence, the correct option is c.

Answer:
b > -16
Step-by-step explanation:
The inequality is given as:
b - 1 > -17
To solve this problem, add +1 to both sides of the expression:
b - 1 + 1 > -17 + 1
Now;
b > -16
So, all values for which b is more than -16 satisfy the solution for this problem.
