Based on the random sample of n=800 observations, we have obtained a sample proportion p(bar =0.44. the goal is to test: h(0: p? 0.48 h9a: p< 0.48 what is the standard error ? rounded to four decimal places

The standard error of a distribution of sample proprtions is defined as the standard deviation of the distribution and is symbolized by

and is calculated by the formula
.

Given a random sample of n = 800 observations and a sample proportion p = 0.44.

To test:


The standard error rounded to four decimal places is given by:
