Answer:
p-value of the statistics = 0.0096
Step-by-step explanation:
Given - The mayor of a town has proposed a plan for the annexation of an adjoining bridge. A political study took a sample of 1500 voters in the town and found that 47% of the residents favored annexation. Using the data, a political strategist wants to test the claim that the percentage of residents who favor annexation is above 44%.
To find - Determine the P-value of the test statistic.
Proof -
Given that,
H0 : p = 0.44
Ha : p > 0.44
Now,
Test Statistics is
z = (p bar - p)/ sqrt(p(1-p)/n)
= (0.47 - 0.44) / sqrt(0.44(1-0.44)/1500)
= 2.34
⇒z = 2.34
So,
p-value = P(Z > z)
= P(Z > 2.34)
= 0.0096
⇒p-value = 0.0096
Answer:
Kira has 40 Jelly beans
Step-by-step explanation:
Morgan and Kira have a number of jelly beans in a ratio 5:3.
The ratio is
Morgan : Kira
5:3
The total proportion is= 5 + 3 = 8
Total number of Jelly beans that they have together is = 64 jelly beans
Hence, the number of Jellybeans that Kira has is calculated as:
5/8 × 64 jelly beans
= 40 jelly beans.
Kira has 40 Jelly beans
Answer:
20
Step-by-step explanation:
This is a right triangle
a² + b² = c²
16² + 12² = x²
256 + 144 = x²
400 = x²
take the square root of both sides
x = 20
