Question

In a survey of 900 organizations. 690 responded that 'the need for collaboration among an increasing number of locators* is a Business driver that led them to implement duo solutions Construct a 95% confidence interval estimate for the population pro pontoon of organizations that indicated 'the need for collaboration among an increasing number of locations" is a business driver that led thorn to implement cloud solutions. A 95% confidence interval estimate for the population proportion is lessthanorequalto pi lessthanorequalto (Round to four decimal places as needed.)

Explanation / Answer

Confidence Interval For Proportion
CI = p ± Z a/2 Sqrt(p*(1-p)/n)))
x = Mean
n = Sample Size
a = 1 - (Confidence Level/100)
Za/2 = Z-table value
CI = Confidence Interval
No. of success(x)=690
Sample Size(n)=900
Sample proportion = x/n =0.7667
Confidence Interval = [ 0.7667 ±Z a/2 ( Sqrt ( 0.7667*0.2333) /900)]
= [ 0.7667 - 1.96* Sqrt(0.0002) , 0.7667 + 1.96* Sqrt(0.0002) ]
= [ 0.7391,0.7943]
