Question

. If n=100, σ =5 then the maximum error with 95% confidence is [ ]​

Answer 1

Step-by-step explanation:

Given . If n=100, σ =5 then the maximum error with 95% confidence is [ ]

• Given n = 100 , σ = 5 we need to find the maximum error with 95% confidence
• So formula for maximum error will be E = Z α/2 x σ / √n
• Now for 95% confidence the value of Z α/2 = 1.96
• Now substituting the given values in the equation we get
•                          E = Z α/2 x σ / √n
•                             = 1.96 x 5 / √100
•                            = 1.96 x 5/10
•                           = 1.96 x 1/2  
•                          = 0.98
• So the maximum error is 0.98
