A correlation is simply used to determine whether a relationship exists between the variables.

<h3>How to illustrate the information?</h3>

The information is incomplete and an overview will be given. The correlation shows the relationship between the variable.

This can be explained in a numerical form that's known as the correlation coefficient. This shows that strength of the relationship.

A cone has a volume of 1570 cubic inches. Which of the following gives the volume of a cylinder with the same radius and same he

Hitman42 [59]

The volume of the cylinder is 4710 cubic inches

Step-by-step explanation:

Volume of the cone = 1570 cubic inches

Volume of cone = 1/3(volume of the cylinder)

So,

Volume of the cylinder = 3(volume of the cone)

Volume of the cylinder = 3(1570)

= 4710 cubic inches

The volume of the cylinder is 4710 cubic inches

A random sample of 100 observations from a quantitative population produced a sample mean of 22.8 and a sample standard deviatio

natima [27]

Answer:

We conclude that the population mean is 24.

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 24

Sample mean, $\bar{x}$ = 22.8

Sample size, n = 100

Alpha, α = 0.05

Sample standard deviation, s = 8.3

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 24\\H_A: \mu \neq 24$

We use Two-tailed z test to perform this hypothesis.

Formula:

$z_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{s}{\sqrt{n}} }$

Putting all the values, we have

$z_{stat} = \displaystyle\frac{22.8 - 24}{\frac{8.3}{\sqrt{100}} } = -1.44$

We calculate the p-value with the help of standard z table.

P-value = 0.1498

Since the p-value is greater than the significance level, we accept the null hypothesis. The population mean is 24.

Now, $z_{critical} \text{ at 0.05 level of significance } = \pm 1.96$

Since, the z-statistic lies in the acceptance region which is from -1.96 to +1.96, we accept the null hypothesis and conclude that the population mean is 24.
