A radio talk show host with a large audience is interested in the proportion p of adults in his listening area who think the dri

vekshin1

Answer:

The margin of error for a 90% confidence interval is 0.075.

Step-by-step explanation:

We are given that he asks listeners to phone in and vote "yes" if they agree the drinking age should be lowered and "no" if not.

Of the 100 people who phoned in, 70 answered "yes."

Let $\hat p$ = sample proportion of people who say yes

So, $\hat p=\frac{X}{n}$ = $\frac{70}{100}$ = 0.70

where, X = Number of people who say yes = 70

n = Number of people phoned in = 100

Now, Margin of error formula for any confidence interval is given by;

Margin of error = $Z_(_\frac{\alpha}{2}_ ) \times \text{Standard of Error}$

where, $\alpha$ = level of significance = 10%

Standard of error = $\sqrt{\frac{\hat p(1-\hat p)}{n} }$

Also, the critical value of x at 5% ( $\frac{\alpha}{2} =\frac{0.10}{2}$ ) level of significance is 1.645.

SO, Margin of Error = $1.645 \times \sqrt{\frac{\hat p(1-\hat p)}{n} }$

= $1.645 \times \sqrt{\frac{0.70(1-0.70)}{100} }$

= 0.075

Hence, the margin of error for a 90% confidence interval is 0.075.
