Based on information from a large insurance company, 67% of all damage liability claims are made by single people under the age

svetoff [14.1K]

Answer:

We conclude that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company.

Step-by-step explanation:

We are given that based on information from a large insurance company, 67% of all damage liability claims are made by single people under the age of 25.

A random sample of 52 claims showed that 43 were made by single people under the age of 25.

Let p = population proportion of claims made by single people

So, Null Hypothesis, $H_0$ : p $\leq$ 67% {means that the insurance claims of single people under the age of 25 is smaller than or equal to the national percent reported by the large insurance company}

Alternate Hypothesis, $H_A$ : p > 67% {means that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company}

The test statistics that will be used here is One-sample z-test for proportions;

T.S. = $\frac{\hat p-p}{\sqrt{\frac{p(1-p)}{n} } }$ ~ N(0,1)

where, $\hat p$ = sample proportion of claims made by single people under the age of 25 = $\frac{43}{52}$ = 0.83

n = sample of claims = 52

So, the test statistics = $\frac{0.83-0.67}{\sqrt{\frac{0.67(1-0.67)}{52} } }$

= 2.454

The value of z-test statistics is 2.454.

Since in the question, we are not given the level of significance so we assume it to be 5%. Now, at 0.05 level of significance, the z table gives a critical value of 1.645 for the right-tailed test.

Since the value of our test statistics is more than the critical value of z as 2.454 > 1.645, so we have sufficient evidence to reject our null hypothesis as it will fall in the rejection region.

Therefore, we conclude that the insurance claims of single people under the age of 25 is higher than the national percent reported by the large insurance company.

Consider the arithmetic sequence where the 15th term is 0 and the 40th term is -50.

ira [324]

Answer:

$a_n=28-2(n-1)$

Step-by-step explanation:

We want to find the formula for this problem in the explicit form of:

$a_n=a_1+d(n-1)$ , where $a_n$ is the nth term, $a_1$ is the first term, and d is the common difference

Here, we can say that the "first term" is the 15th term, which is 0, so instead of a_1, we have a_15. The nth term is the 40th term, which is -50, so instead of a_n, we have a_40:

$a_n=a_1+d(n-1)$

$a_{40}=a_{15}+d(40-15)$

$-50=0+d(25)$

d = -2

Now, we need to find the first term:

$a_{15}=a_1+d(15-1)$

$0=a_1+(-2)(14)$

a_1 = 28

Finally, our equation is: $a_n=28-2(n-1)$

Hope this helps!

Answer:

In everyday terms and everyday language, rates of change have meaning. For example, the rates of change for some of the examples above can be worded in this manner.

Example 1

Word Problem:

You are at an amusement theme park with your 10 year old child. You bought a ticket for �1/2 day, but your child wants to stay another 4 hours after the �1/2 day is used. The admissions office can accommodate your child's additional time but the rate is $ 15 an hour. How much will it cost to purchase the additional 4 hours at this rate?

Solution to the Word Problem:

$15 / 1 Hour = $x / 4 Hours

x= 4 x 15 = $60

Answer: It will cost you an additional $60 for 4 more hours of fun for your child.

Example 2

Word Problem:

You are following a recipe for a cake for your church group's get together. This recipe calls for 3 tsp of baking powder to every 6 cups of flour. How many tsp would you add to 24 cups of flour?

Solution to the Word Problem:

3 tsp : 6 cups OR 3 tsp / 6 cups OR 3 tsp is to 6 cups

3 tsp / 6 cups = x tsps / 24 cups

6x = 24 x 3 = 76

6x = 24 x 3 = 72 / 6 = 12 4/16 = 12 tsps

Answer: You will need 12 tsps. of baking powder for 24 cups of flour which is enough to make 4 cakes for the church group's get together.
