An article a florida newspaper reported on the topics that teenagers most want to discuss with their parents. the findings, the results of a poll, showed that 46% would like more discussion about the family's financial situation, 37% would like to talk about school, and 30% would like to talk about religion. these and other percentages were based on a national sampling of 531 teenagers. estimate the proportion of all teenagers who want more family discussions about school. use a 99% confidence level.

From the information given, the 99% confidence interval estimate of the proportion of all teenagers who want more family discussions about school is (0.316, 0.424).

In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.

In which

z is the z-score that has a p-value of .

The information given are as follows:

99% confidence level

So , z is the value of Z that has a p-value of , so .

The lower limit of this interval is:

The upper limit of this interval is:

The 99% confidence interval estimate of the proportion of all teenagers who want more family discussions about school is (0.316, 0.424).

A similar problem is given at link

Confidence Interval for the proportion of all teenagers who want more family discussions about school is ( 31.6% , 42.4% )

Step-by-step explanation:

Given:

Number of teenagers in the sample , n = 531

Percentage of people like more discussion about family's financial situation = 46%

Percentage of people like more discussion about school, = 37%

Percentage of people like more discussion about religion = 30%

To find:  Confidence Interval for the proportion of all teenagers who want more family discussions about school

Level of confidence, α = 100 - 99 = 1% = 0.01

We know that

Critical Value for given level of significance, = 2.58

The Standard Deviation,

The Required Confidence Interval is,

Hence the Require confidence interval is ( 0.316 , 0.424 ).

Therefore, Confidence Interval for the proportion of all teenagers who want more family discussions about school is ( 31.6% , 42.4% )

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.
