Answer:
The company's chocolate bars weigh 1.6 ounces on average.
Step-by-step explanation:
We are given that a company claims that its chocolate bars weigh 1.6 ounces on average.
It took many large samples, and each time the mean weight of the sample was within the 95% confidence interval.
95% confidence level means a range of values that you can be 95% certain contains the true mean of the population.
Thus by definition we can say that The company's chocolate bars weigh 1.6 ounces on average.
Hence Option B is correct.
Hey there,
So let's start off with one part of this equation
. . . 
would be 0.01.
So, we have 0.01 has our answer (so far).
Then we would do 7.1 × 0.01, this would give us
. . .
0.071.Your correct and final answer would be

Hope this helps you!

Answer:
The correct answer to the following question will be "0.438".
Step-by-step explanation:
Just because Mrs. Gomes finds around 40% of students in herself high school are studying chemistry.
Although each student becomes independent of one another, we may conclude:
"x" number of the students taking chemistry seems to be binomial to p = constant probability = 0.40
Given:
Number of surveys
= 12
Exactly 4 students have taken chemistry:



On substituting the above equation, we get the probability of approximately "0.438".
So that the above would be the appropriate answer.
