Answer: a) 683 b) 1067
Step-by-step explanation:
The confidence interval for population proportion is given by :-
a) Given : Significance level :
Critical value : 
Margin of error : 
Formula to calculate the sample size needed for interval estimate of population proportion :-
Hence, the required sample size would be 683 .
b) If no estimate of the sample proportion is available then the formula to calculate sample size will be :-
Hence, the required sample size would be 1067 .
Plug in the values for x and y to check.
-6>8-10
-6>-2
Final answer: False
This is because -6<-2. Remember that for negative numbers, the number with the greater absolute value is less.
Answer:The mean increases but the median stays the same.
Step-by-step explanation:
201 + 233 + 237 +255 +269+277+306 mean is 257 and median is 255
225 +233 + 237 +255 +269+277+306 mean is 260 and median is 255
<span> G(f(x)) = 2(x^2 -1) + 3
= 2x^2 + 1
subsitute 2
= 9
Hence, the answer is 9</span>
6*8= 48
Git rid of one "48" and replace it with "6" and the empty blank you would enter "8"
