Given : There are 5 Snickers, 10 Baby Ruths, 13 Milky Ways, 12 Twixs and17 Almond Joys in a bowl of candy.
Total candy bars :
Probability of getting a Milky Way bar=
Using Binomial distribution , the probability of getting success in x trials is given by:-
, where p uis probability of success in each trial and n is sample size.
If you randomly select n= 5 candy bars, then the probability you select exactly 2 Milky Way bars Will be :_

Answer:
The 90% confidence interval for the support of Sanders by millenials is between 53% and 57%.
Step-by-step explanation:
In this question we have to calculate a confidence interval (90% CI) on the proportion of millenials that had a favorable opinion on Sanders.
The sample size is n=1,754.
The p-hat, taken from the poll, is
The estimated standard deviation is equal to:
For a 90% CI, the z-value is z=1.645.
Then, the confidence interval is
