Answer:
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Explanation:
Below are the null and alternative hypothesis,
Null hypothesis: p= 0.65
Alternative Hypothesis: p < 0.65
Test statistic for text of significance
z = (pcap –p)/ ![\sqrt{ [p*(1-p)/n]}](https://tex.z-dn.net/?f=%5Csqrt%7B%20%5Bp%2A%281-p%29%2Fn%5D%7D)
z = (0.576 – 0.65)/ ![\sqrt{[0.65×1-0.65)/125]}](https://tex.z-dn.net/?f=%5Csqrt%7B%5B0.65%C3%971-0.65%29%2F125%5D%7D)
z = 1.73
P- value Approach
p-value = 0.0414
As P-value < 0.05, we reject the null hypothesis

Answer:
1:(D), 2:(D), 3:(D)
Explanation:
1) When a rock is exposed to heat and pressure, it becomes a metamorphic rock. This is correct, because this is the process that forms a metamorphic rock.
2) A rock becomes sediment through weathering and erosion. In this question, they are not asking you to explain the process of sedimentary rock formation, they are asking you how a rock becomes sediment. The process of weathering and erosion breaks down a rock, and turns that rock into smaller peices, which therefore, through the process of compaction and cementation forms a sedimentary rock.
3) A fern is a land plant. It is not found in the sea and there is not enough information given to tell whether or not the area was hot or cold. This leaves us with D. We can tell that this fossil is a land fossil because ferns do not grow in the ocean.
Hope I could help, and best of luck!
