Step-by-step explanation:
Answer:
2/3
Step-by-step explanation:
10/15 equals 2/3
Answer:
McDonalds = 75/500
Popeyes = 50/500
chipotle = 225/500
Burger King = 125/500
Wendy's = 25/500
Step-by-step explanation: Since 20 people were in group questioned originally & you want to know how many from 500 you would divide 500 by 20 for 25. Then multiply by 25.
Answer:
I would say yes, reset the machine, because the sample mean of 124.9 ounces is out of the 95% confidence interval
Step-by-step explanation:
It depends on your alpha level of test.
Would you be fine if the 124.9 ounces is in a 95% confidence interval?
we know u = 125 ounces, σ = 0.30 ounces
sample mean E = 124.9 ounces n = 40
Our test statistic is Z = [(E - u) / σ ]* which follows a Standard Normal
so...
Check if P ( -1.96 < Z < 1.96) = 95% so
Z = [(E - u) / σ ]* = [ (124.9 - 125)/ 0.3 ] *
Z = (-0.1/0.3)* 6.3245 = -2.1 ... this is out of the 95% confidence interval
I would say yes, reset the machine, because the sample mean is out of the 95% confidence interval
