Find mean p hat

WebStep 1:Find P-hat by dividing the number of people who responded positively. In this case, 380/1000 people (38%) responded positively. In this case, 380/1000 people (38%) responded positively. Step 2: Find the z-score that goes with the given confidence interval 90% , you get a z-score (a critical value) of 1.645. WebBecause the mean of the sampling distribution of (p hat) is always equal to the parameter p, the sample proportion (p hat) is an UNBIASED ESTIMATOR of (p). The standard deviation of (p) hat gets smaller as the sample size n increases because n appears in the denominator of the formula for the standard deviation. That is, (p hat) is less ...
