A random sample of 50 observations results in 20 successes C

A random sample of 50 observations results in 20 successes. Calculate the point estimate of the population proportion of successes. (Round your answer to 2 decimal places.) Point estimate Calculate the point estimate of the population proportion of failures. (Round your answer to 2 decimal places.) Point estimate

Solution

a)

p^ = x/n = 20/50 = 0.40 [ANSWER]

*******************

b)

q^ = 1 - x/n = 1 - 0.40 = 0.60 [ANSWER]
