Answer:
The option which is an exception is;
c) The sample sizes are large
Step-by-step explanation:
Here the requirement to perform a two sample t procedure are as follows;
1. The two samples have equal variance, hence the variance should be known
2. The samples for which the two sample t procedure is performed must be independent
3. The data are in alignment with the normal distribution probability
4. The samples are random samples taken from the different respective population
Since the sample size is known, we do not assume that the sample size are large.
Therefore options a), b) and d) are all correct except option c).
Answer: Lena will be able to make 54 cupcakes.
Step-by-step explanation:
If 1/3 cups has t make 6 cups , then we can set up a proportional relationship and find out how much 3 cups of milk can make.
Cross multiply
1/3x = 18 Multiply both sides by 3.
x = 54
It is C. 165 I’m pretty sure
So hmm check the picture below
we know the vertex is at the origin, and the focus point is below it, that means two things, the parabola is vertical and it's opening downwards
notice the distance "p", from the vertex to the focus point, is just 7 units, however, since the parabola is opening downwards, the "p" value will be negative, so p = -7
