15+(-15)=0 I hope this helps
Answer:
1.165.
Step-by-step explanation:
We have that to find our
level, that is the subtraction of 1 by the confidence interval divided by 2. So:

Now, we have to find z in the Ztable as such z has a pvalue of
.
So it is z with a pvalue of
, so 
Now, find the margin of error M as such

In which
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
. So


So the correct answer is:
1.165.
Answer:
In each muffin there are 1.53oz
Step-by-step explanation:
The first step is to get the weight of just one muffin. If the package contains six muffins we must divide the total weight by six.

The weight of just one muffin is 3oz.
Now, the problem says that blueberry high-fiber muffins contain 51 % dietary fiber by mass, which means that we must calculate the 51% of 3oz. We must take into account that 51% equals 51/100 which is 0.51. The equation would be:

Finally, in each muffin there are 1.53oz of fiber.
