$\bf \cfrac{4}{5}+\cfrac{8}{9}\implies \stackrel{\textit{using the LCD of 45}}{\cfrac{(9)4~~+~~(5)8}{45}}\implies \cfrac{36+40}{45}\implies \cfrac{76}{45}\implies 1\frac{31}{45}$

What is the minimum number of clients the travel agent should survey? Note that z=1.96 for a 95% confidence interval.

slega [8]

Answer:

121

Step-by-step explanation:

Given data as per the question

Standard deviation = $\sigma$ = 840

Margin of error = E = 150

Confidence level = c = 95%

For 95% confidence, z = 1.96

based on the above information, the minimum number of clients surveyed by the travel agent is

$n = (\frac{z\times \sigma}{E})^2$

$= (\frac{1.96\times 840}{150})^2$

= 120.47

= 121

hence, the 121 number of clients to be surveyed

Therefore we applied the above formula to determine the minimum number of clients
