a. The population proportion p= b. The sample proportion p-hat= c. Find the standard error

Question

A candy company claims that 31% of the candies are orange. We randomly sample 100 candies. We wish to know the probability our sample is 29% orange candies or less. Round answers to 2 decimal places and answer numerically (0.31, not 31%)

Answer 1

standard error = sqrt(p*(1-p)/n))

p = population proportion = 0.31

n = sample size

standard error = sqrt(0.31 * 0.69/100) = 0.05
