Answer:
Reject H0; there is significant evidence that the proportion of site users who get their world news on this site has changed since 2013 and is significantly different from 45%
Step-by-step explanation:
Sample size, n = 3603
x = 1697
Phat = x/n = 1697/3603 = 0.4709 =47.09%
H0 : p = 0.45
H1 : p > 0.45
The test statistic :
(phat - p) / sqrt[(p(1 - p)) /n]
(0.4709 - 0.45) / sqrt[(0.45(0.55))/3603]
0.0209 / 0.00828810932
Test statistic = 2.5217
The Pvalue :
Using the Pvalue from Test statistic calculator ; α = 0.05 ;
Pvalue at 95% confidence = 0.005839
Pvalue < α ;
Hence, we reject the Null
Therefore, we conclude that the sample gives evidence that the proportion of site users who get their world news on this site has changed since 2013.
The area of a rectangle is Length multiplied by Width
So plug the numbers in to find the width
1/2 = 2/3*W
Solve as follows:
1/2 divided by 2/3 =3/4 so,
W=3/4
The width of the parking lot is 3/4 of a mile
Answer:
EFK and IKH are vertical angles
Step-by-step explanation:
Vertical angles touch at a point and have the same lines, just extended
EFK and IKH are vertical angles
FKG and IKJ are vertical angles
GKH and EKJ are vertical angles
1 1/2
3/2 is equal to 1 1/2 because 2 goes into 3 once with 1 left over.
