Answer:

4.3 g

Step-by-step explanation:

An outlier is a data point that strays far from the average of the group.

The other data points are all close to 3.

See how 4.3 is way farther from 3 than all the rest?

kherson [118]

Answer:

People are more likely to avoid approaching difficult situations as they fear failure or looking bad to others if they get it wrong. They lack the point of view of being looked upon as brave for attempting something that others avoid.

olchik [2.2K]

Answer: $7.25 at part-time job

$9.00 every time lawn mowed

so he would get 33.33 day so we will just say 33 times to get 300 dollars if he gets $9 for mowing. And 41.37 hours to get $300 and he would have to use x and y graph to find the boundary line.

Consider a drug testing company that provides a test for marijuana usage. Among 310 tested​ subjects, results from 28 subjects w
Naily [24]

Answer:

z=\frac{0.0903 -0.1}{\sqrt{\frac{0.1(1-0.1)}{310}}}=-0.569  

The p value for this case can be calculated with this probability:

p_v =P(z  

Since the p value is higher than significance level we don't have enough evidence to conclude that the true proportion is significantly less than 0.1

Step-by-step explanation:

Information given

n=310 represent th sample selected

X=28 represent the subjects wrong

\hat p=\frac{28}{310}=0.0903 estimated proportion of subjects wrong

p_o=0.1 is the value to verify

\alpha=0.05 represent the significance level

t would represent the statistic

p_v represent the p value

System of hypothesis

We want to test the claim that less than 10 percent of the test results are wrong ,and the hypothesis are:  

Null hypothesis:p\geq 0.1  

Alternative hypothesis:p < 0.1  

The statistic is given by:

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

Replacing the info we got:

z=\frac{0.0903 -0.1}{\sqrt{\frac{0.1(1-0.1)}{310}}}=-0.569  

The p value for this case can be calculated with this probability:

p_v =P(z  

Since the p value is higher than significance level we don't have enough evidence to conclude that the true proportion is significantly less than 0.1

Factor 1/3 out of 1/3p-2/3 please answer this! Easy 20 points!
Tju [1.3M]

Answer:

\frac{1}{3} (\frac{1}{p} - 2)

Step-by-step explanation:

Given the equation = \frac{1}{3p} - \frac{2}{3}

Required: To factor out 1/3;

\frac{1}{3p} - \frac{2}{3}

1/3 is common to both sides;

So, 1/3 is a common factor

\frac{1}{3} (\frac{1}{p} - 2)

To solve for the value of p;

\frac{1}{3} (\frac{1}{p} - 2) = 0

\frac{1}{p} - 2 = 0

\frac{1}{p} = 2

1 = 2p

p = \frac{1}{2}
