Tigers have weights that are N(500, 20 ). ( pounds ) You win 2 tigers. Find the probability that your tigers have an average weight that is more that 510 pounds .
Make a 95% confidence interval for the percentage of fish that swim backward in an hour given that you watched 500 fish swim backward for an hour and 100 of these fish swam backwards.
Solution-
1) the probability that your tigers have an average weight that is more that 510 pounds-
0.2398
◆calculation-
2) the 95% confidence interval for the percentage of fish that swim backward in an hour is-
( 0.165 , 0.235 )
