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:
Number of total arrangement of beads = 2,520
Step-by-step explanation:
Given:
Number of beads in necklace = 8 beads
Find:
Number of total arrangement of beads
Computation:
Changing beads is a cyclic permutation,
So,
Formula to find number of total arrangement in cyclic permutation
(n-1)!/2 , where n = number of item
So,
(n-1)!/2
Number of total arrangement of beads = (8-1)!/2
Number of total arrangement of beads = (7)!/2
Number of total arrangement of beads = (7 x 6 x 5 x 4 x 3 x 2 x 1) / 2
Number of total arrangement of beads = 5,040 / 2
Number of total arrangement of beads = 2,520
