SpyIntel [72]

Answer: 1308

Step-by-step explanation:

Given : Level of confidence = 0.97

Significance level : \alpha=1-0.97=0.03

Critical value : z_{\alpha/2}=2.17

Margin of error : E=0.03

If prior proportion of population is unknown , then the formula to find the population proportion is given by :-

n=0.25(\dfrac{z_{\alpha/2}}{E})^2

\Rightarrow n=0.25(\dfrac{2.17}{0.03})^2=1308.02777778\approx1308

Hence, the minimum sample size needed =1308

25/10 as a mixed number
Anvisha [2.4K]
A mixed number is an integer and a fraction that is less than one (remember that x/x = 1.) 
To simplify 25/10, calculate how many times 10 goes into 25 by dividing 25 by 10. The answer is 2 with a remainder of 5 (10 x 2 = 20, 25-20 = 5).
The mixed number is 2 and 5/10, which simplifies to 2 1/2.
