The poll found that 38% of a random sample of 1012 American adults said they believe in ghosts. What is the lower bound for a 90
Brrunno [24]

Answer:

The lower bound for a 90% confidence interval for the percentage of all American adults who believe in ghosts is 0.3549

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

For this problem, we have that:

n = 1012, \pi = 0.38

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

The lower limit of this interval is:

\pi - z\sqrt{\frac{\pi(1-\pi)}{n}} = 0.38 - 1.645\sqrt{\frac{0.38*0.62}{1012}} = 0.3549

The lower bound for a 90% confidence interval for the percentage of all American adults who believe in ghosts is 0.3549

What is the domain and range of each relation?
LUCKY_DIMON [66]

Answer:

\text{Domain of}R_1=\{-2,0,2,4\}  and \text{Range of}R_1=\{-3,-1,0\}

\text{Domain of}R_2=\{-3,-1,0,3\}  and \text{Range of}R_2=\{-1,0,1,2,3\}

Step-by-step explanation:

Domain is the set of input values or x-values.

Range is the set of output values or y-values.

According to the relation mapping diagram, the relation is

R_1=\{(-2,-3),(-2,-1),(0,0),(2,0),(4,-3)\}

So,

\text{Domain of}R_1=\{-2,0,2,4\}

\text{Range of}R_1=\{-3,-1,0\}

In the graph 5 points are plotted. So, the relation is  

R_2=\{(-3,1),(-1,-1),(0,0),(3,2),(3,3)\}

So,

\text{Domain of}R_2=\{-3,-1,0,3\}

\text{Range of}R_2=\{-1,0,1,2,3\}
