Create a table, chart, or diagram that you can use to help you decide which hypothesis test you need to use (selecting from: pop

ulation proportion, a population mean, two proportions from independent samples, two means from dependent samples, and two means from independent samples). Explain your table, chart, or diagram so that someone new to statistics could use it to select the appropriate hypothesis test.

A hypothesis testing is a statistical inference that uses data from a sample to draw conclusions.

<h3>What is hypothesis testing?</h3>

It should be noted that hypothesis testing simply means a statistical act where an assumption is made regarding a parameter.

In this case, a hypothesis testing is a statistical inference that uses data from a sample to draw conclusions. The null hypothesis predicts no effect while the alternative hypothesis states the research predictions.

a campus radio station surveyed 500 students to determine the types of music they like. the survey revealed that 206 like rock,
tester [92]

The probability that the randomly selected student exactly likes exactly one of the three types is 0.72

<h3>What is a probability?</h3>

It is a branch of mathematics. It is used to concern numerical descriptions to occur an event. Theoretical probability, Experimental probability, Axiomatic probability are the three types of probability we have. Probability can be expressed in proportions. Probability deals in finding the occurrence of an event. The theoretical probability is based on possible chances of something that happen. Probability refers to the term synonymously as a possibility. The probability that is based on series of experiments is known as Experimental probability. The set of axioms which are applied to all the types of probability is known as Axiomatic probability.

Number of persons who likes rock music be R

Number of persons who likes Country music be C

Number of persons who likes Jazz music be J

R = 206

C = 158

J = 119

R ∩ C = 26 - 7 = 19

R ∩ J = 27 - 7 = 20

C ∩ J = 19 - 7 = 12

R ∩ C ∩ J = 7

Thus, number that liked only jazz music is;

n(only jazz) = J - [(R ∩ J) + (C ∩ J) + (R ∩ C ∩ J)]

n(only jazz) = 119 - (20 + 12+ 7)

n(only J) = 119-39=80

Number of students that liked only Rock music;

n(only Rock) = R - [(R ∩ C) + (R ∩ J) + (R ∩ C ∩ J)]

n(only Rock) = 206 - (19 + 20 + 7)

n(only R) = 206-46=160

Number of students that liked only country music;

n(only country) = C - [(R ∩ C) + (C ∩ J) + (R ∩ C ∩ J)]

n(only country) = 158- (19 + 12 + 7)

n(only C) = 158-38=120

The probability that the randomly selected student exactly likes exactly one of the three types is,

P= (80+160+120)/500

P=360/500

P=0.72

Therefore, the probability is 0.72.

What’s the volume of the cone
Likurg_2 [28]

Answer:

The volume of cone can be:

V = 216\pi

    or

V \approx 678.584

Step-by-step explanation:

-Use the formula to find the volume of a cone:

V = \frac{1}{3} \pi r^2h

-Use both the radius and the height for the formula:

V = \frac{1}{3} \pi 6^218

-Then, you solve:

V = \frac{1}{3} \pi 6^218

V = \frac{1}{3} \times \pi \times 6^2 \times 18

V = \frac{1}{3} \times \pi \times 36 \times 18

V = \frac{1}{3} \times \pi \times 648

V = \frac{1}{3}\pi \times 648

V = \frac{648}{3} \pi

V = 216\pi \approx 678.584

So, the answer can be 216\pi or 678.584 .
