Answer: (-2, 11/6)
Step-by-step explanation:
Answer:
Now we can calculate the p value. Since is a bilateral test the p value would be:

Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true proportion of residents favored annexation is higher than 0.72 or 72%
Step-by-step explanation:
Information given
n=900 represent the random sample selected
estimated proportion of residents favored annexation
is the value that we want to test
represent the significance level
z would represent the statistic
represent the p value
Hypothesis to test
The political strategist wants to test the claim that the percentage of residents who favor annexation is above 72%.:
Null hypothesis:
Alternative hypothesis:
The statistic for this case is given by:
(1)
Replacing the data given we got:
Now we can calculate the p value. Since is a bilateral test the p value would be:

Since the p value is lower than the significance level of 0.05 we have enough evidence to conclude that the true proportion of residents favored annexation is higher than 0.72 or 72%
Answer:
45 yards by 24 yards
Step-by-step explanation:
You would have to first find out how many 2.5 increments are in each of the two lengths. Then multiply that number by 15
0.275
275 is in the thousandths place, therefore the numerator will be 275 and the denominator will be 1000.
275/1000 is our new fraction, but we must simplify. 5 goes into both numbers, so 275 divided by 5 is 55 and 1000 divided by 5 is 200. 55/200 is our new fraction. We keep dividing by 5 until you can't anymore.
So when that's done the simplified fraction is 11/40.
