A random sample is selected from a population with mean = 100 and standard deviation = 10. Determine the mean and standard devia
jenyasd209 [6]

The mean and standard deviation of the x sampling distribution for each of the following sample sizes will be N(100,10/\sqrt{41} ), N(100,10/\sqrt{130} ).

<h3>What is the distribution of the sample mean for large samples?</h3>

Suppose X has a distribution with mean \mu and standard deviation \sigma,then,

the distribution of the mean of samples of size n, drawn from the values of X, is normally distributed with a mean equal to the mean of X, and a standard deviation equal to \sigma/\sqrt{n}

Symbolically, we write it as:

X \sim N(\mu, \sigma) \implies \overline{X} \sim N(\mu,\sigma/\sqrt{n} )

A random sample is selected from a population with a mean = of 100 and a standard deviation = of 10.

The mean and standard deviation of the x sampling distribution for each of the following sample sizes.

If N=41

X \sim N(100, 10) \implies \overline{X} \sim N(100,10/\sqrt{41} )

If N=130

X \sim N(100, 10) \implies \overline{X} \sim N(100,10/\sqrt{130} )

9.4 the tangent ratio<br> please help on #27 and 28
Ilya [14]

Answer/Step-by-step explanation:

27.

✔️Sin 23 = opp/hyp

Sin 23 = t/34

34*sin 23 = t

t = 13.3

✔️Cos 23 = adj/hyp

Cos 23 = s/34

s = 34*cos 23

s = 31.3

28.

✔️Sin 36 = opp/hyp

Sin 36 = s/5

s = 5*sin 36

s = 2.9

✔️Cos 36 = adj/hyp

Cos 36 = r/5

r = 5*cos 36

r = 4.0

29.

✔️Sin 70 = opp/hyp

Sin 70 = w/10

w = 10*sin 70

w = 9.4

✔️Cos 70 = adj/hyp

Cos 70 = v/10

v = 10*cos 70

v = 3.4
