P(D) = P(C)
We know that in total all (a,b,c,d) equal 1
So .28+.56+C+D=1
We can interpret it as
.84 + 2x = 1
x=.08
So P(D) = .08
Answer:
x:-2
y:2
Step-by-step explanation:
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.
