you buy butter 4.13 a pound one portion of onion requires 1.7 oz of butter how much dose the butter for one portion cost

yuradex [85]

Answer:

The butter for one portion of onion costs $ 0.44

Step-by-step explanation:

Let's recall that 1 pound = 16 ounces, therefore we have:

Cost of one pound of butter = $ 4.13

Cost of sixteen ounces of butter = $ 4.13

How much dose the butter for one portion cost?

We can use Direct Rule of Three for answering this question, as follows:

Ounces Cost

16 4.13

1.7 x

**************************

16x = 4.13 * 1.7

16x = 7.021

x = 7.021/16

x = 0.44 (Rounding to the next cent)

The butter for one portion of onion costs $ 0.44

Answer:

The proportions differ from those reported in the survey.

Step-by-step explanation:

The Chi-square goodness of fit test would be used to determine whether the proportions differ from those reported in the survey.

The hypothesis for the test can be defined as follows:

H₀: The proportions does not differ from those reported in the survey.

Hₐ: The proportions differ from those reported in the survey.

Assume that the significance level of the test is, α = 0.01.

The Chi-square test statistic is given by:

$\chi^{2}=\sum\limits^{n}_{i=1}{\frac{(O_{i}-E_{i})^{2}}{E_{i}}}$

Consider the Excel sheet provided.

The Chi-square test statistic value is 191.32.

The p-value of the test is:

$p-value=P(\chi^{2}_{(n-1)}>191.32)\\\\=\text{CHISQ.DIST.RT}(191.32,2)\\\\=0.0000$

The p-value of the test is very small. The null hypothesis will be rejected at 1% level of significance.

Thus, concluding that the proportions differ from those reported in the survey.
