a.
To find: If the two packages of pasta likely have the same advertised weight and to find out the manufacturer whose quality control appears better.
a.
Answer to Problem 10.4.1P
It is very much likely that both packages of pasta have the same advertised weight, Rafaello Pasta’s quantity control appears better.
Explanation of Solution
Given Information: Two relevant histograms.
Analyzing the two histograms,
In histogram of Cucina Leonardo, the data is widely dispersed but the data is concentrated around
Rafaello Pasta’s quantity control appears better because data lies around
Thus, it is very much likely that both packages of pasta have the same advertised weight, Rafaello Pasta’s quantity control appears better.
b.
To infer: The two population distribution shapes by sketching smooth curves across the tops of the histograms and describe the shapes.
b.
Answer to Problem 10.4.1P
Result is bell shaped formation, this implies that distribution is symmetric.
Explanation of Solution
Given Information: Two relevant histograms.
Sketch:
Sketching smooth curves across the tops of histograms,
Both result in bell shaped formation, this implies that distribution is symmetric and most of the data is clustered around a center and as one moves away from center frequency keeps on decreasing. In this case, center is the advertised weight and other data values are a result of negligence during preparation and filling pasta in packages.
Thus, result is bell shaped formation, this implies that distribution is symmetric.

- Compare the interest earned from #1 (where simple interest was used) to #5 (where compound interest was used). The principal, annual interest rate, and time were all the same; the only difference was that for #5, interest was compounded quarterly. Does the difference in interest earned make sense? Select one of the following statements. a. No, because more money should have been earned through simple interest than compound interest. b. Yes, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. c. No, because more money was earned through simple interest. For simple interest you earn interest on interest, not just on the amount of principal. d. Yes, because more money was earned when compounded quarterly. For compound interest you earn interest on interest, not just on the amount of principal.arrow_forwardCompare and contrast the simple and compound interest formulas. Which one of the following statements is correct? a. Simple interest and compound interest formulas both yield principal plus interest, so you must subtract the principal to get the amount of interest. b. Simple interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest; Compound interest formula yields only interest, which you must add to the principal to get the final amount. c. Simple interest formula yields only interest, which you must add to the principal to get the final amount; Compound interest formula yields principal plus interest, so you must subtract the principal to get the amount of interest. d. Simple interest and compound interest formulas both yield only interest, which you must add to the principal to get the final amount.arrow_forwardSara would like to go on a vacation in 5 years and she expects her total costs to be $3000.

Select the correct choice below and, if necessary, fill in the answer box(es) to complete your choice. ○ A. No, b is not in {a₁, a2, 3} since it cannot be generated by a linear combination of a₁, a2, and a3. B. No, b is not in (a1, a2, a3} since b is not equal to a₁, a2, or a3. C. Yes, b is in (a1, a2, a3} since b = a (Type a whole number.) D. Yes, b is in (a1, a2, 3} since, although b is not equal to a₁, a2, or a3, it can be expressed as a linear combination of them.
