Students in a statistics class are conducting a survey to estimate the mean number of units students at their college are enroll

Andrew [12]

Using the t-distribution, as we have the standard deviation for the sample, it is found that the 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

<h3>What is a t-distribution confidence interval?</h3>

The confidence interval is:

$\overline{x} \pm t\frac{s}{\sqrt{n}}$

In which:

$\overline{x}$ is the sample mean.

t is the critical value.

n is the sample size.

s is the standard deviation for the sample.

The critical value, using a t-distribution calculator, for a two-tailed <em>95% confidence interval</em>, with 49 - 1 = <em>48 df</em>, is t = 2.0106.

Hence:

$\overline{x} - t\frac{s}{\sqrt{n}} = 12.2 - 2.0106\frac{1.6}{\sqrt{49}} = 11.7$

$\overline{x} + t\frac{s}{\sqrt{n}} = 12.2 + 2.0106\frac{1.6}{\sqrt{49}} = 12.7$

The 95% confidence interval for the number of units students in their college are enrolled in is (11.7, 12.7).

Una tractomula se desplaza con rapidez de 69 km/h. Cuando el conductor ve una vaca atravesada en medio de la carretera, acciona

irinina [24]

Responder:

El remolque del tractor no atropellará a la vaca.

Explicación:

Dado lo siguiente:

Velocidad del tractor remolque: 69 km / h

Tiempo necesario para detenerse después de aplicar los frenos = 4 segundos

Distancia de vacas desde el remolque del tractor = 25 metros

Por lo tanto, la distancia recorrida por el remolque del tractor después de aplicar los frenos:

Velocidad del tractor remolque / Tiempo

69 km / h = (69 * 1000) m / 3600s = 69000m / 3600s = 19.17m / s

(19,17 m / s ÷ 4 s) = 4,8 m

Como la distancia de la vaca está más lejos (25 m), el remolque del tractor no pasará por encima de las vacas

After the big bang, protons, electrons, and neutrons were formed through

vlada-n [284]

As the space expanded, big bang happened and resulted to the formation of protons, electrons, and neutrons through nuclear fusion that scattered like fog in the universe. During the fusion, the sun and other stars generate heat and light. The light elements break up into dense plasma and the temperature cooled, which form matter.

In addition, nuclear fusion create a reaction in which two or more atomic nuclei are combined such as protons and neutrons collided to make deuterium, an isotope of hydrogen and when deuterium combined, it will make helium.
