Mode, is talking about which number shows up the most times in a set of number.

For example, the number 1 will be the mode in the set [1,1,1,2,2,3].

-------------------------------------------------------------------------------------------------------

Now.. looking at your question, first order the numbers.

[0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6, 6, 6, 6, 7, 8, 8, 9, 10, 12]

After re-ordering, we can see that both 2 and 6 shows up 4 times, two more than the next numbers that have the next largest amount of numbers (1, 4 and 8, each having 2 numbers)

However, now you are adding another 6 into the set.

[0, 1, 1, 2, 2, 2, 2, 4, 4, 5, 6, 6, 6, 6, 6, 7, 8, 8, 9, 10, 12]

Now, 6 shows up 1 more time than the next largest set of number, 2.

6 will be your new mode.

C. The mode will change to one number is your answer, and that number is 6

hope this helps

C) The mode will change to one number

Explanation: Mode is the number or numbers that appear the most. Before you added an extra 6, the mode was 2 & 6 because there was 4 2's & 4 6's but when you added another 6, the mode changed to 6 because the 6 appeared 5 times.

Calculate to the nearest 1/10th meter the radius of a 7th, 12th, and 30th hectare circular plot. [Work

Tcecarenko [31]

Answer:

For a 7 hectare plot, the radius is 149.3 m.

For a 12 hectare plot, the radius is 195.5 m.

For a 30 hectare plot, the radius is 309.1 m.

Step-by-step explanation:

For a circular plot of area A, the radius is

[tex]r=\sqrt{A/\pi}[\tex]

One hectare is equal to 10,000 m2.

For a 7 hectare plot, the radius is

[tex]r=\sqrt{7*10,000/3.14}\\r=\sqrt{22,293}=149.3[\tex]

For a 12 hectare plot, the radius is

[tex]r=\sqrt{12*10,000/3.14}\\r=\sqrt{38,216}=195.5[\tex]

For a 30 hectare plot, the radius is

[tex]r=\sqrt{30*10,000/3.14}\\r=\sqrt{95,541}=309.1[\tex]

The University of Arkansas recently approved out of state tuition discounts for high school students from any state. The student

Fudgin [204]

Answer:

$z=\frac{0.872 -0.9}{\sqrt{\frac{0.9(1-0.9)}{180}}}=-1.252$

$p_v =P(z$

So the p value obtained was a very low value and using the significance level given $\alpha=0.1$ we have $p_v>\alpha$ so we can conclude that we have enough evidence to FAIL to reject the null hypothesis, and we can said that at 10% the proportion of students who came from Arkansas or a bordering state is not significantly lower than 0.9

b. Fail to reject H0; conclude that the new policy increases the percentage of students from states that don’t border Arkansas

Step-by-step explanation:

Data given and notation n

n=180 represent the random sample taken

X=157 represent the students who came from Arkansas or a bordering state

$\hat p=\frac{157}{180}=0.872$ estimated proportion of students who came from Arkansas or a bordering state

$p_o=0.9$ is the value that we want to test

$\alpha=0.1$ represent the significance level

Confidence=90% or 0.90

z would represent the statistic (variable of interest)

$p_v$ represent the p value (variable of interest)

Concepts and formulas to use

We need to conduct a hypothesis in order to test the claim that the true proportion is higher or not than 0.9.:

Null hypothesis: $p\geq 0.9$

Alternative hypothesis: $p < 0.9$

When we conduct a proportion test we need to use the z statistic, and the is given by:

$z=\frac{\hat p -p_o}{\sqrt{\frac{p_o (1-p_o)}{n}}}$ (1)

The One-Sample Proportion Test is used to assess whether a population proportion $\hat p$ is significantly different from a hypothesized value $p_o$ .

Calculate the statistic

Since we have all the info requires we can replace in formula (1) like this:

$z=\frac{0.872 -0.9}{\sqrt{\frac{0.9(1-0.9)}{180}}}=-1.252$

Statistical decision

It's important to refresh the p value method or p value approach . "This method is about determining "likely" or "unlikely" by determining the probability assuming the null hypothesis were true of observing a more extreme test statistic in the direction of the alternative hypothesis than the one observed". Or in other words is just a method to have an statistical decision to fail to reject or reject the null hypothesis.

The significance level provided $\alpha=0.1$ . The next step would be calculate the p value for this test.

Since is a left tailed test the p value would be:

$p_v =P(z$

b. Fail to reject H0; conclude that the new policy increases the percentage of students from states that don’t border Arkansas
