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:
75%
Step-by-step explanation:
The image is 4 : 3 = 12 : 9. It is displayed on a screen that is 16 : 9, so it occupies 12/16 = 3/4 of the screen.
75% of the screen area is occupied
Answer:
$12
Step-by-step explanation:
Cost of basketball tickets will be 26*$19.25=$500.5
Cost of symphony tickets will be 22*$23.25=$511.5
Total cost incurred will be $500.5+511.5=$1012
Budget was $1000
Extra money past budget will be $1012-$1000=$12
Therefore, Lyle exceeded budget by $12
