If the proportion of american adults who believe that America is ready for a woman president is .70 what are the mean and standard deviation for the number of people who believes that america is ready for a sample size of 1000?
find the standard deviation and mean.
Homework Answers
Solution
Given that,
p = 0.70
1 - p = 1-0.70=0.30
n = 100
= p =0.70
standard deviation and mean. (proportion)
= 
[p(
1 - p ) / n] =
[(0.70*0.30) / 100]=0.0458
=0.046

A 2020 Pew Research poll found that 65% of U.S. adults believe that President Donald Trump was too slow to make major steps to stop the spread of the coronavirus. Let's assume that 0.65 is the population proportion. Suppose random samples of 100 U.S. adults are randomly selected, and the proportion of each sample is found. Suppose you find a sample of 100 adults in which 62% believe that President Donald Trump was too slow to make major steps to...
