0.000837051 is the correct answer
Both- that is not the correct answer. There must be another way to do the problem
I didn't round it. I submitted .13326 ; I also tried 13.326
No, we're supposed to submit answers to 4 decimal places.
I've tried that answer as well but the program where we submit our answers tell me that's incorrect.
I am taking an Elementary Statistics course.. I need to know the right answer and how to get the right answer to these problems. We are able to use excel to solve the problems. Any help would be appreciated!
Question 5:
Cans of regular Coca-Cola are labeled as containing 12oz, and a statistics student would like to see if this 12oz number is really believable. To do this, the student measured the contents of 8 randomly chosen cans, and found the mean volume to be 12.1.
Assuming that cans of Coke are filled so that the actual amounts are normally distributed with a mean of 12.00oz and a standard deviation of 0.09oz. Find the probability that a sample of 8 cans will have a mean amount of at least 12.1 oz.
I have no idea how to get the correct answer for this problem.. I ave tried multiple times and ways.
Question 8:
Scores for men on the verbal portion of the SAT-I test are normally distributed with a mean of 509 and a standard deviation of 112.
(a) If 1 man is randomly selected, find the probability that his score is at least 581.
I was able to figure this one out and the answer is 0.2601584 .
(b) If 20 men are randomly selected, find the probability that their mean score is at least 581.
I am confused on how to find this answer..
