Suppose the true proportion of voters in the county who support a restaurant tax is 0.54. Consider the sampling distribution for

Eva8 [605]

Answer:

The correct answer is:

(a) 0.54

(b) 0.0385

Step-by-step explanation:

Given:

Restaurant tax,

p = 0.54

Sample size,

n = 168

Now,

(a)

The mean will be:

⇒ μ $\hat{p}= p$

$=0.54$

(b)

The standard error will be:

$\sigma \hat{p}$ = $\sqrt{[\frac{p(1-p)}{n} ]}$

= $\sqrt{[\frac{(0.54\times 0.46)}{168} ]}$

= $\sqrt{[\frac{(0.2484)}{168} ]}$

= $0.0385$

A wire is first bent into the shape of a rectangle with width 5in and length 13in. Then the wire is unbent and reshaped into a t

MAXImum [283]

Total length of the wire = 2*13 + 2*5 = 26 + 10 = 36 in.

so length of each side of the triangle would be 36/3 = 12 ins.

In a class of 40 students, 5 like neither Nokia nor

Vikki [24]

Answer:

No student liked only Nokia

Step-by-step explanation:

The information can be illustrated as shown on the Venn diagram.

The number of students who liked only Nokia is x.

The sum of all regions in the Venn diagram should be 40.

We add all to get:

$5 + 5 + 30 + x = 40$

$40 + x = 40$

$x = 40 - 40$

$x = 0$

Therefore no one liked only Nokia
