If you are constructing a 95% confidence interval for a normally distributed population when your sample size is 10, what value

Nuetrik [128]

This is something you'll need a T table for, or a calculator that can compute critical T values. Either way, we have n = 10 as our sample size, so df = n-1 = 10-1 = 9 is the degrees of freedom.

If you use a table, look at the row that starts with df = 9. Then look at the column that is labeled "95% confidence"

I show an example below of what I mean.

In that diagram, the row and column mentioned intersect at 2.262 (which is approximate). This value then rounds to 2.26

<h3>Answer: 2.26</h3>

Julia wrote a linear equation in standard form as –6x – 3y = 10. Arthur noticed that the equation was not written in standard fo

aleksklad [387]

Answer:

Option A - $6x +3y = -10$ is the standard form of the equation.

Step-by-step explanation:

Given : Linear equation - $-6x -3y = 10$

To convert into the standard form.

Standard form of the equation is in form Ax+By=C

So to convert this equation into the standard form we have to multiply both side of the equation by -1, so that the value for A is positive.

After multiplying by -1 the form is

$-6x\times (-1) -3y\times(-1)= 10\times(-1)$

$6x +3y = -10$ is the standard form of the equation.

Therefore, Option A is correct.

Assume that the number of hours of daylight in New Orleans in 1994 is given by the function D(x) = 7 3 sin 2π 365 x + 35 3 , whe

Bas_tet [7]

Answer:

Here, the given function that represents the number of hours of daylight in New Orleans in 1994 is,

$D(x) = \frac{7}{3} \sin \frac{2\pi }{365}x + \frac{35}{3}$

Where,

x = the number of days after March 21

The number of days from 1 January to march 21 = 80

If x = -80, then,

$D(-80) = \frac{7}{3} \sin \frac{2\pi }{365}(-80) + \frac{35}{3}$

$=\frac{7}{3} \sin (-\frac{160 \pi}{365}) + \frac{35}{3}$

$=-\frac{7}{3} \sin (\frac{160 \pi}{365}) + \frac{35}{3}$

$=-\frac{7}{3}(0.98130)+\frac{35}{3}$

$\approx 9.38$

Therefore, the number of hours of daylight on January 1 are 9.38.

The number of days from march 21 to may 4 = 44

If x =44, then,

$D(44) = \frac{7}{3} \sin \frac{2 \pi}{365}(44) + \frac{35}{3}$

$=\frac{7}{3} \sin (\frac{88 \pi}{365}) + \frac{35}{3}$

$=\frac{7}{3}(0.6870) + \frac{35}{3}$

$\approx 13.27$

Therefore, the number of hours of daylight on May 4 are 13.27.

The number of days from October 28 to may 4 = 221

If x = 221, then,

$D(221) = \frac{7}{3} \sin \frac{2 \pi}{365}(221) + \frac{35}{3}$

$=\frac{7}{3} \sin (\frac{442 \pi}{365}) + \frac{35}{3}$

$=\frac{7}{3}(-0.6152)+\frac{35}{3}$

$\approx 10.23$

Therefore, the number of hours of daylight on October 28 are 10.23.
