The consumer group's claim that the difference in proportions has a mean of 0.03 is incorrect
<h3>How to calculate the difference in proportion</h3>
The table entries are given as:
Kernels Proportion that Popped
Brand R 100 0.92
Brand S 200 0.89
The proportions of the samples that will pop for both brands are given as:
Calculate the difference of both proportions
So, we have:
This means that:
The difference in proportions has a mean of 0.05
Hence, the claim of the consumer group is incorrect

There is a property that states that vertical angles are congruent with each other. By definition, vertical angles are opposite angles when two intersecting lines are drawn. From the figure, angle (3y - 30) is equal to angle (2x + 4). But first, let's determine x. One revolution is equal to 360°. So,
360 = 2(2x + 4) + 2(4x - 6)
Solving for x,
x = 91/3
Now, solving for y:
3y - 30 = 2x + 4
3y - 30 = 2(91/3) + 4
y = [2(91/3) + 4 + 30]/3
y = 31.56
