Salaries for Actuaries Nationwide graduates entering the actuarial field earn $40,000. A college placement officer feels that this number is too low. She surveys 36 graduates entering the actuarial field and finds the average salary to be $41,000. The population standard deviation is $3000. Can her claim be supported at
a = 0. 05?
We can rule out the null hypothesis, allowing her assertion to stand because the value of P is less than 0.05(P<0.05) if the salaries for actuaries Nationwide graduates entering the actuarial field earn $40,000.
What is Z-test?The Z test is a parametric procedure that is used on data that is dispersed in a normal fashion. For testing hypotheses, the z test can be used on one sample, two samples, or proportions. When the population variance is known, it analyzes if the means of two big groups are dissimilar.
We have Salaries for actuaries Nationwide graduates entering the actuarial field earn $40,000.
Let's suppose the null hypothesis is H0
[tex]\rm H0: \mu = 40,000\\[/tex]
An alternative hypothesis is H1
[tex]\rm H1: \mu > 40,000[/tex]
Using Z-test
[tex]\rm Z_{test} = \frac{X' - \mu}{{\sigma} }[/tex]
We have
X' = 41,000, [tex]\mu = 40,000[/tex], and [tex]\sigma = 500[/tex],
[tex]\rm Z_{test} = \frac{41000-40000}{{500}}[/tex]
[tex]\rm Z_{test} = \frac{1000}{500 }[/tex]
[tex]\rm Z{test }= 2[/tex]
P-value from the Z-table for [tex]\rm Z{test }= 2[/tex]
P(Z = 2) = 0.02275
Since the value of p is less than 0.05 We can rule out the null hypothesis, allowing her assertion to stand.
Thus, we can rule out the null hypothesis, allowing her assertion to stand because the value of P is less than 0.05(P<0.05) if the salaries for actuaries Nationwide graduates entering the actuarial field earn $40,000.

high temperatures all year with lots of rain
Answer:
Tropical region.
Explanation:
Since the question was posted under Geopgraphy, I'm assuming that you want the region where high temperatures with lots of rain lasts all year.
It'll be in the tropical region / trophics. These are the regions that lie near the equator (between the Tropic of Cancer & Tropic of Capricon). They get the maximum amount of sunlight / the sun's rays (the Earth bulges about here because it's in the middle..the Earth is ellipsoidal in shape) & hence have high temperatures. Also, rainfall is quite prominent here. Some countries that lie in this region are: South India, Sri Lanka, Brazil, Thailand, Peru etc.

A volcanic eruption is an event that would lead to the formation of what type of rock?
metamorphicmetamorphic , ,
chlorophyllchlorophyll , ,
igneousigneous , ,
sedimentarysedimentary , ,
Answer:
The answer to this question would be igneous rock
Explanation:
Igneous rocks are rocks that are made from cooled lava, and lava comes from volcanos.
Metamorphic rock is rock that was created by heat and pressure
Sedimentary rock is created when tiny little rock sediments interact with water, and then that water acts as a glue and binds that sediment together. Over thousands of years, those sediments undergo the process of compaction and cementation, and that's how the sediments transform into sedimentary rock.
Chlorophyll is not a rock at all, it's actually a chemical in plants that make the plants look green.

A buried body of shale is subjected to differential stress, causing clay minerals to realign and produce slate. This is an example of a. diagenesis. b. erosion. c. metamorphism. d. weathering.
Answer:
c. metamorphism
Explanation:
A buried body of shale is subjected to differential stress, causing clay minerals to realign and produce slate. This is an example of metamorphism. The correct option is C.
A shale undergoes different phases of metamorphism as it is subjected to increased pressure and heat; initially, it changes into slate, then phyllite, then schist, and lastly gneiss.
What is burial metamorphism?Sedimentary rocks that have experienced diagenesis can undergo burial metamorphism when they are buried even farther. As a result of the heat and pressure that underlying sediments and sedimentary rocks impose, diagenesis progresses into burial metamorphism, a comparatively mild type of metamorphism.
Rocks' textures and mineral composition can change as a result of metamorphism, but new mineral assemblages are never created. When differential stress is applied to a body of subsurface shale at temperatures higher than 200 C, clay minerals develop in their preferred orientation, creating slate.

Answer:
China should be correct
Explanation:
China is the country that has the greatest altitude difference in the world. It has the largest elevation span. The Tibetan Plateau is partially to blame for the country's high average elevation.
What is an altitude difference?Relief is the height elevation difference between two geographical features. For instance, we could utilize relief to represent the height, slope, and direction of a mountain range. Or, we might just state flatness is the antithesis of relief.
Height: The vertical distance between the measurement point and the point from which the observation was made. Altitude is the vertical distance from the measurement place to mean sea level.
