Answer:

both option (A) & (B) is description of given distribution.

Step-by-step explanation:

The outlier is a point which lies differently or far away from rest points in datasets or distribution.

Here we can self-time for one apple on the 10th day is outlier present in the distribution. Thus Option (A) is correct.

We divide the heterogeneous group into many homogeneous groups, these homogeneous group is known as Cluster. It can be seen naturally.

Also, here distribution is divided into many clusters and we can see given distribution has many clusters and one of them is from 4 to 6 days. Thus Option (B) is also a correct option here.

The single apple on day 10 is an outlier because it is all by its self and the there is a cluster from 4 to 6 because there are multiple apples on days 4, 5, and 6 so your answers would be A and B :)

The equation ​ yˆ=−0.37x2+6.15x+52.3 ​ approximates the average temperature in October in degrees Fahrenheit at an agricultural
sweet-ann [11.9K]

Answer:

The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

Solution:

Number of hours after 5 a.m.: x

At 10 a.m.→x=10-5→x=5

​ yˆ=−0.37(5)^2+6.15(5)+52.3

yˆ=−0.37(25)+30.75+52.3

yˆ=−9.25+30.75+52.3

yˆ=73.8

Answer: The best estimate for the average temperature in October at 10 a.m. is 73.8 degrees Fahrenheit.

A political candidate has asked you to conduct a poll to determine what percentage of people support her. If the candidate only
Snezhnost [94]

Answer:

At sample size of 752 is needed.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of \pi, and a confidence level of 1-\alpha, we have the following confidence interval of proportions.

\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}

In which

z is the zscore that has a pvalue of 1 - \frac{\alpha}{2}.

The margin of error is:

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

90% confidence level

So \alpha = 0.1, z is the value of Z that has a pvalue of 1 - \frac{0.1}{2} = 0.95, so Z = 1.645.

What size of sample is needed?

A sample size of n is needed.

n is found when M = 0.03.

We do not have a estimate for the true proportion, so we use \pi = 0.5, which is when we are going to need the largest sample size.

M = z\sqrt{\frac{\pi(1-\pi)}{n}}

0.03 = 1.645\sqrt{\frac{0.5*0.5}{n}}

0.03\sqrt{n} = 1.645*0.5

\sqrt{n} = \frac{1.645*0.5}{0.03}

(\sqrt{n})^{2} = (\frac{1.645*0.5}{0.03})^{2}

n = 751.67

Rounding up

At sample size of 752 is needed.
