Answer:
121
Step-by-step explanation:
Given data as per the question
Standard deviation = = 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

Set up a proportion:
y = 35 when x = 7
y = ? when x = 10
To get x from 7 to 10, you have to multiply by . Therefore, you do the same to 35, and you get:
And your answer is 50 :)
