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.

Which statement correctly describes a feature of the rock cycle? rocks are preserved through the process. rocks change from one type to another. different rock groups are not related to one another. the rock cycle follows a specific order.
Answer: The answer is B. Rocks change from one type to another.
Explanation:
The rocks change from one type to another. Thus, the second statement correctly describes a feature of the rock cycle.
What is a rock cycle?The three main kinds of rock—igneous, metamorphic, and sedimentary—are formed and decomposed according to various applications of heat and pressure over time, and this process-based network is known as the rock cycle.
For instance, when heat and pressure are applied to solid rock shale, slate is the result. The granite undergoes further metamorphosis until it becomes gneiss with increasing heat and pressure. The rock will fully melt if heated any higher, then reform as an igneous rock.

Why is the global community trying to prevent climate change? List 3 reasons
First Reason:
Delayed efforts to mitigate either carbon dioxide or short-lived climate pollutant emissions will have negative, and potentially irreversible, consequences for global warming, rising sea levels, food security, and public health.
Second Reason:
Due to their relatively short lifetime in the atmosphere, ranging from a few days to a few decades, reducing short-lived climate pollutants can rapidly slow the rate of global temperature rise, complement efforts to mitigate carbon dioxide emissions and keep warming below 2°C.
Third Reason:
The Climate and Clean Air Coalition’s measures can cut methane emissions by at least 40% and black carbon by up to 70% by 2030, and virtually eliminate (99.5%) high-global warming potential hydrofluorocarbons altogether by 2050 (all compared to 2010 levels).
