Answer:

C. 7.2

Step-by-step explanation:

D = $\sqrt{(-1-3)^2+(-2-4)^2}$

The water content of a soil volume is measured four times gravimetrically by oven drying. The mean value of the water content is

expeople1 [14]

Answer:

99% confidence interval for the soil water content is determined by

(0.19474, 0.26926)

Step-by-step explanation:

Explanation:-

Given mean of the sample = 23.2% = 0.232

Given standard deviation of the sample = 1.0% =0.01

Given sample size 'n' =4

Degrees of freedom = n-1 =4-1 =3

critical value = 0.01

$t_{\frac{0.01}{2} } = t_{0.005} =7.4534$

99% confidence interval for the soil water content is determined by

$((x^{-} - t_{0.005} \frac{S.D}{\sqrt{n} } , (x^{-} + t_{0.005} \frac{S.D}{\sqrt{n} })$

$((0.232 - 7.4534\frac{0.01}{\sqrt{4} } , (0.232 + 7.4534 \frac{0.01}{\sqrt{4} })$

( 0.232 -0.03726 , 0.232 +0.03726)

(0.19474, 0.26926)

Final answer:-

99% confidence interval for the soil water content is determined by

(0.19474, 0.26926)

A family has two children. If the genders of these children are listed in the order they are born, there are four possible outco

scZoUnD [109]

Answer:

P(X=0) = 0.25

P(X=1) = 0.50

P(X=2) = 0.25

Step-by-step explanation:

The possible outcomes of this event are: BB, BG, GB and GG.

There is one out of four events (GG) in which there are two girls (X=2).

There is one out of four events (BB) in which there are no girls(X=0).

There are two out of four events (GB and BG)) in which there is one girl (X=1).

Therefore, the probability distribution of X is:

P(X=0) = 1/4 = 0.25

P(X=1) = 2/4 = 0.50

P(X=2) = 1/4 = 0.25
