Which of the following is FALSE about the Central Limit Theorem?

It is only valid if the population distribution is Normal

Choose the best answer

There is a convenience sampling bias present for Suzy & John

Which is NOT a similarity between the t-distribution and the standard Normal distribution?

Both depend on degrees of freedom

When using the rejection region approach, when should you reject the null hypothesis?

SRS of 1000 rates from 100 randomly selected branches in U.S

Choose the best answer.

If you toss a fair coin 7 times and get 7 heads, the 8th toss MUST be tails. Is this true?
Yes. Law of large #s says 50% are tails, so tails is overdue
Yes. With so many heads, a tail MUST be next.
No. You cannot predict next toss from previous toss.
No, the coin is not really fair so it could be heads again
