Complete Question
Ava read an article claiming that 10% of people in her county were senior citizens, and she wondered if this held true for residents in her city. She took a random sample of 225 people from her city to test H0 : p = 0.10, where p is the proportion of people in her city that are senior citizens. Ava found that approximately 14% of those sampled were senior citizens. She conducted an appropriate significance test, and the resulting test statistic was z ≈ 1.89 z. Assume that the conditions for inference were met.calculate the p-value for Ellie's significance test
Answer:
The p-value is
Step-by-step explanation:
From the question we are told that
The percentage of senior citizens is p = 0.10
The sample size is
The sample proportion is
The test statistics is
The null hypothesis is
The alternative hypothesis is
Generally the p-value is mathematically represented as
From the z-table

Answer:
135
Step-by-step explanation:
To answer this question you would write down 105+165 you'll get 260 then to know how much wilma will have to pay you would take the amount wilma pays monthly which is 395 and the answer you got from 105+165 which is 260 and add 395-260 so, 395-260=135
The radius would be 8. If the circumference is 2r, that means that it is 2 times the radius. If you are trying to solve for the radius, you just divide the circumference by 2 :)
