In a previous experiment we tested the amount of female and male fish born under
extreme heat conditions. Our sample size was 562 embryos. Of those embryos 311
were born female and 251 were born male. What would be the expected frequency
of this data set for chi-squared test?

You are playing a paired dice game with your brother, and he has placed all his bets
on the extreme number (2s, 3s, 11s, and 12s) whereas you placed your bets on the
middle numbers (5s, 6s, 7s, and 8s). However, as the game goes on, you think that
the dice are landing on the extreme numbers more often than should be allowed
strictly by chance. In fact, he's winning! You accuse him of using a loaded dice, and
in order to test it, you keep track of all the dice rolls for 100 rolls and run a ChiSquare
analysis. The p-value you get back is 0.47. Which of the following conclusions should
you draw?
A. Your brother is definitely cheating.
B. Your brother is most likely cheating.
C. Your brother is probably not cheating.
D. Your brother is definitely not cheating.✔✔C. Your brother is probably not cheating.

C. Creating too many possible candidates for what is in the box to be solved during
class.

the best fit judging by your observations alone.✔✔D. A potential bias towards the
objects presented being what is in the box instead of the best fit judging by your
observations alone.
