Answer: 0.355,0.405)
Step-by-step explanation:
Given : Significance level :
Number of subjects (n) = 2455
Number of surveys returned = 931
The probability of surveys get return will be :-
The confidence interval for proportion is given by :-
Hence, the 99% confidence interval for the proportion of returned surveys : (0.355,0.405)
Given:
The function is:
The function f(x) is multiplied by a factor of 2 and then 3 is added to the function.
To find:
The effect on the graph of the function.
Solution:
The transformation is defined as
.... (i)
Where, k is stretch factor and b is vertical shift.
If 0<k<1, then the graph compressed vertically by factor k and if k>1, then the graph stretch vertically by factor k.
If b>0, then the graph shifts b units up and if b<0, then the graph shifts b units down.
It is given that the function f(x) is multiplied by a factor of 2 and then 3 is added to the function. So, the new function is:
...(ii)
On comparing (i) and (ii), we get
, it means the graph is vertically stretched by a factor of 2.
, it means the graph is shifted up 3 units.
Therefore, the correct option is D.
