Suppose that 1 month before the election a random sample of 500 registered voters are surveyed. From this sample 270 indicate th
Aleonysh [2.5K]

Answer:

[ 0.4964, 0.5836 ]

Step-by-step explanation:

Data provided in the question:

Total sample size = 500

person voting for smith = 270

thus,

P( person voting for smith ), p = \frac{270}{500} = 0.54

Confidence level = 95%

now,

standard error, SE = \sqrt{\frac{p(1-p)}{n}

or

SE = \sqrt{\frac{0.54(1-0.54)}{500}

or

SE = 0.0223

now,

Confidence interval = p ± ( z × SE )

here,

z value for 95% confidence interval is 1.96

Confidence interval = [ 0.54 - ( 1.96 × 0.0223 ), 0.54 + ( 1.96 × 0.0223 ) ]

= [ 0.54 - 0.0436 , 0.54 + 0.0436 ]

= [ 0.4964, 0.5836 ]

The value of 2 x 10¹⁴ is___times the value of 4 x 10⁶
Lunna [17]

Step-by-step explanation:

2 x 10¹⁴ = 200 000 000 000 000 while

4 x 10⁶ = 4 000 000

so 200 000 000 000 000 000 / 4 000 000 = 50 000 000

that means the value of 2 x 10¹⁴ is 5 x 10⁷ times the value of 4 x 10⁶
