Step-by-step explanation:
Given that,
By using the table, the critical values of t will be:
=
Now,
The confidence interval will be:
=
By putting the values, we get
=
=
Im not 100% sure but i kinda see 156000 as you answer
Both of these conditions must be true in order for the assumption that the binomial distribution is approximately normal. In other words, if and then we can use a normal distribution to get a good estimate of the binomial distribution. If either np or nq is smaller than 5, then a normal distribution wouldn't be a good model to use.
side note: q = 1-p is the complement of probability p
Answer:
Steven ate 3 pieces
Step-by-step explanation:
If Johnny ate 3/4 , then Steven at 1 - 3/4 or 1/4
12 * 1/4 = 3
Steven ate 3 pieces
12/68= 43/d
Divide 43 by 12 which is 3.583
then multiply 68 by 3.583
So d is 243.6
