The symbol is the Greek letter "z." Z is used in the context of a standard normal distribution to represent the number of standard deviations away from the mean a specific value is.
Now, let's discuss the one-mean z-test and how to express the p-value in terms of z.
a. Left-tailed: In a left-tailed test, we are interested in the area under the curve to the left of the specified value of z. The p-value can be expressed as P(Z < z), which represents the probability that a standard normal random variable Z is less than the observed value of the test statistic z.
b. Right-tailed: In a right-tailed test, we are interested in the area under the curve to the right of the specified value of z. The p-value can be expressed as P(Z > z), which represents the probability that a standard normal random variable Z is greater than the observed value of the test statistic z.
c. Two-tailed: In a two-tailed test, we are interested in the area under the curve in both tails, which means both the left and right sides of the specified value of z. The p-value can be expressed as 2 * P(Z > |z|), where |z| is the absolute value of the test statistic z. This represents the sum of the probabilities in both tails.

What form of energy is responsible for producing changes that occur in Earth’s hydrosphere?
Answer:
the sun because energy from the Sun heats the Earth unevenly. As a result, convection currents develop in the atmosphere and ocean. These redistribute heat in the atmosphere and oceans.
Answer: Hydropower is created when rapidly flowing water turns turbines inside a dam, generating electricity. Nuclear energy is produced at power plants by the process of nuclear fission. The energy created during nuclear reactions is harnessed to produce electricity.

Biology.
Answer:
You can separate them according to the shapes of their beaks.
Some have longer, pointier beaks whilst others have flat and short beaks.
This is because they eat different things: seeds vs worms and insects.
This means that the shape of their beak is an adaptation (it enables their survival) because it makes it easier for them to consume food.
This is known as occupying different niches in the habitat, because even if they all live in one area, they will eat different things, meaning that they will always have enough food to survive.

Answer:
B. White Blood Cells

I missed the word innate for a sec there, but then I looked up whether stomach acid is part of the immune system at all and realized my mistake.
The innate immune system is the part of the immune system one is born with, and we're not born with white blood cells. Those build up over time as we are exposed to pathogens.
