An insurance company selected samples of clients under 18 years of age and over 18 and recorded the number of accidents they had in the previous year. The results are shown below.
| Under Age of 18 | Over Age of 18 |
| n1 = 500 | n2 = 600 |
| Number of accidents = 180 | Number of accidents = 150 |
We are interested in determining if the accident proportion for the
Under 18 is larger than the proportion for Over
18.
Let pu represent the proportion under and po
the proportion over the age of 18. The null
hypothesis is
| A |
pu is greater than po |
|
| B |
pu is not equal to po |
|
| C |
pu is less than or equal to po |
|
| D |
pu is greater than or equal to po |
Homework Answers
Below are the null and alternate hypothesis
H0: pu <= po
Ha: pu > po
The alternate hypothesis is the researcher's claim and the opposite of it is the null hypothesis.
Hence option C is correct.
pu is less than or equal to po

In a previous poll, 36% of adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Suppose that, in a more recent poll, 378 of 1108 adults with children under the age of 18 reported that their family ate dinner together seven nights a week. Is there sufficient evidence that the proportion of families with children under the age of 18 who eat dinner together seven nights a week has decreased?...

Independent random samples of size n1=38 and n2=86 observations, were selected from two populations. The samples from populations 1 and 2 produced x1=18 and x2=13 successes, respectively. Define p1 and p2 to be the proportion of successes in populations 1 and 2, respectively. We would like to test the following hypotheses: H0:p1=p2 versus H1:p1≠p2 (a)To test H0 versus H1, which inference procedure should you use? A. Two-sample z procedure B. One-sample z procedure C. One-sample t procedure D. Two-sample t...

(1 point) An insurance company states that at least 86% of its claims are settled within 30 days. A consumer group selected a random sample of 73 of the company's claims to test this statement. They found that 60 of the claims were settled within 30 days. Does the consumer group have evidence to disbelieve the insurance company's claim? 1. Write the hypotheses to test if the rate of claims settled within 30 days is significantly less than 86%. H0H0:...
