After the air has descended on the east (leeward) side of the Coast Range back to sea level, what is the air temperature

lesya692 [45]

Answer:

The air temperature gets warmer.

Explanation:

When the air descends on the east side of the Cosra Strip back to sea level, it ends up releasing a large amount of latent heat, as it needs to go through a condensation process when it reaches the windward mountain. This causes the air to descend at a higher temperature than it did when it was rising from the other side. In other words, the temperature of the air is higher than the temperature it was at sea level.

The water cycle transports a plethera of microorganisms, and many of them are harmful for human beings. These include bacteria, protozoa, viruses, and lavae of high-ordered parasytes. Some of the aforementioned are Giardia, Cyptospordium, Shigella, E. coli, hepatitis A virus, and enterovirus.

Waters can also carry chemical wastes such as pesticides, and heavy metals dissolved in them. It is common to hear about acid rain as a result of pollution, and it originates as a result of mixing sulphur dioxide and nitrogen oxide with water molecules in the atmosphere.

There are several technological improvements over the past 100 years that have made the availability of clean water to communities a lot easier, and not only depend on boiling water. Filtration is the most common practice, it traps most unwanted particles and microorganisms, but it should be accompanied with chemical disinfection, which uses halogens to oxidize essential celluar structures and enzymes. In the present, chemical disinfection can even be achieved with adding a pill to a specific volume of water.

ACT scores of a sample of UTC students are shown below. Student ACT Score A 22 B 28 C 20 D 21 E 28 F 23 G 26 a. Compute the mean

alisha [4.7K]

Solution :

a). Let x denotes ACT scores.

ACT scores = $\{ 22,28,20,21,28,23,26 \} ; n = 7$

Mean, $(\overline x)=\frac{\sum x_i}{n}$

$=\frac{168}{7}=24$

Sample variance, $S^2=\frac{1}{n-1}\left(\sum x_i^2-n\overline x^2 \right)$

$=\frac{1}{6}(4098-7 \times 24^2)$

$=\frac{66}{6}$

= 11

b). To test whether or not variance of ACT scores of population (say $\sigma^2$ ) of the UTC students is significantly more than 8.

Consider the hypothesis :

$H_0: \sigma^2 \leq8$ vs $H_a: \sigma^2 >8$

It is a right tailed test and α = 0.05

We have

$x^2_{n-1} = \frac{(n-1)s^2}{\sigma^2}$

So test statics is

$x^2_7=\frac{(7-1)11}{8}$

$=\frac{6 \times 11}{8}$

= 8.25

Since our $\text{test statistics is less than the critical value }$ and it falls in a acceptation region, hence we fail to reject $H_0$ and conclude that variance is not greater than 8 significantly.
