Answer: D.
Step-by-step explanation:
Answer:
Part A:
n=6591.87≅6592
Part B:
n=6765.06≅6765
Step-by-step explanation:
In order to calculate the sample size we use the following estimated Sample proportion formula:
Where:
p is the previous estimate
q is the 1-p
Z is the distribution
E is the margin
At 90% Confidence significance level is 0.1/2=0.05
Z at 0.05 or 5% =1.645
Part A:
p=0.42
q=1-p=1-0.42=0.58
Z=1.645
E=0.01
n=6591.87≅6592
Part B:
Since no prior estimate is given we assume p =0.5 and q=0.5
n=6765.06≅6765
Answer:
d
Step-by-step explanation:
A. Between 500 cm and 700 cmB. Between 550 cm and 650 cmC. Between 5.0 cm and 6.0 cmD. Between 5.5 cm and 6.4 cm A B C D
to round off to the nearest cm of 6. the value must be between 5.5 and 6.4
To round off to the nearest whole number, look at the first number after the decimal, if it is less than 5, add zero to the units term, If it is equal or greater than 5, add 1 to the units term.
F(x)=5x^3-2x^2+3
=5 2^3 - 2 2^2 +3
=5 (8) - 2 (4) +3
= 40 - 8 + 3
= 35
answer is A.35
