Chapter 2 (9): Estimating a Point Estimate for the Population Proportion

1. Samplingdistribution of p

1.1. Is approximately normal, with mean = p and standard deviation, op

1.2. Provided np(1-p) >= 10.

2. Estimating a population proportion

2.1. Obtain a point estimate for the Population Proportion

2.2. The value of a statistic that estimates the value of a parameter

3. Level of Confidence- the expected number of proportion of intervals that will contain the parameter

3.1. Construct and Interpret Confidence Intervals

3.2. Consists of an interval of numbers based on a point estimate~ point estimate +/- margin of error

3.3. ~ (1-a) x 100%
