Compute the standard error for sample proportions from a population with proportion p= 0.55 for sample sizes of n=30, n=100 and n=1000 . Round your answers to three decimal places.

Given Information:

Population proportion = p =  0.55

Sample size 1 = n₁ = 30

Sample size 2 = n₂ = 100

Sample size 3 = n₃ = 1000

Required Information:

Standard error = σ = ?

Step-by-step explanation:

The standard error for sample proportions from a population is given by

Where p is the population proportion and n is the sample size.

For sample size n₁ = 30

For sample size n₂ = 100

For sample size n₃ = 1000

As you can notice, the standard error decreases as the sample size increases.

Therefore, the greater the sample size lesser will be the standard error.

lo.lll

step-by-step explanation:

yes. we do proportions in probabilities.
