Question

q: In a huge drawer, there are 50 red and 100 blue balls, we throw the sock back into the drawer each time.

After 10 trials, you got 5 red balls and start to doubt that the number of red balls was not specified correctly.

* State the statistical null hypothesis and alternative hypothesis and explain under which circumstances you would believe that the number of number of red balls was told incorrectly.

* Is it possible to claim with a probability of 60% that the information on the colour proportions was wrong?
-----------------------------------------------------------
* If there were equally many red and blue balls in the drawer, what would be the probability to get 5 blue balls in 5 trials?
p =---------------------------------
