Answer:

Question 2: B- 4n-3 < or equal to 21

Question 3: D- n> or equal to 6

Step-by-step explanation:

You got question 2 wrong because the keyword in the question is at most which means you should use the inequality sign less than or equal to. You can search this up online too. All you have to search on google is "at most inequality sign" and it will automatically bold at most for you and explain the definition.

Question number 3 is correct. Answer choice D

If you can please name me the brainliest that would be much appreciated. Thanks and Good Luck!

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.
