Computing population proportion


Assignment:

Assume the following data represents a population of 50 values. Values equal to 1 indicate that a particular attribute is present, a value equal to 0 indicates the attribute is not present.
1......1......1......1......1......1......1......1......0......0
0......1......1......0......0......1......1......1......0......1
0......1......1......1......1......1......1......1......1......0
1......1......1......1......1......1......1......0......1......1
0......1......1......1......1......1......1......1......1......1

a. Compute the population proportion.
The population proportionate is the fraction of values in a population, which have a specific attribute. Population proportionate = X number of items having the attribute divided by N, the population size.

b. A random sample of 15 items produced the following numbers: 1 1 1 0 0 1 0 0 1 1 0 0 0 1 0. Compute the sample proportion and the sampling error present in your sample.

c. What is the range of extreme sampling error for a sample of 15 taken from this population?

d. How would the range of extreme sampling error change if the sample size was set to 30? Discuss the advantages of having a larger sample size.
