(b) 4,445
Step-by-step explanation:
If the researcher would like to be 95% sure that the obtained sample proportion would be within 1.5% of p (the proportion in the entire population of U.S. adults), what sample size should be used?
Given a=0.05, |Z(0.025)|=1.96 (check standard normal table)
So n=(Z/E)^2*p*(1-p)
=(1.96/0.015)^2*0.5*0.5
=4268.444
Take n=4269
Answer:(b) 4,445
Answer:
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
Step-by-step explanation:
The 15% off represents percentage discount. The relationship between percentage discount and total cost is given by the equation;
Actual cost - (Percentage discount) Actual cost = Total cost
The correct options are;
(29.99 + 18.65 + 32.59) 0.85 = 0
(29.99 + 18.65 + 32.59) - 0.15(29.99 + 18.65 + 32.59) = 0
Answer:
C. 88 in.
Step-by-step explanation:
This is because the equation for the circumference of a circle is pi times diameter. To get the diameter, multiply the radius by 2. Then do 28*3.14 to get the circumference of the circle then round your answer to get the nearest whole number which is 88 in.
