Step-by-step explanation:
The confidence interval for population mean is given by :-
, where is the sample proportion, n is the sample size , is the critical z-value.
Given : Significance level :
Sample size : n= 85
Critical value :
Sample proportion:
Now, the 99% confidence level will be :
Hence, the 99% confidence interval estimate of the true proportion of families who own at least one DVD player is
128 degrees.
An angle's supplement, when added to the original angle, will form a straight (180 degree) angle.
Answer:
Step-by-step explanation:
as given in question that a > 0 so
if we put a=1
we get g(x) = f(x)
now put a =2
we get
g(x) = 2 f(x)
here we can see that g(x) would always be greater than or equals to f(x)
so we can say that the graph of g(x) will never be narrower than graph of g(x)
