Explanation:
Fixed sample size:
In this fixed sample size the data is studied and checked in order to find a relationship. The benefits it is easy to produce, and with it less reliable outcomes can be given.
Sequential procedures:
→Sequential procedures helps while we are collecting the data.
→At an interim analysis, data collection can be stopped whenever the results are convincing enough to conclude an effect is present.
→Or otherwise the more data can be collected, or if needed the study can be terminated whenever it is extremely unlikely the predicted effect will be observed if data collection would be continued.
→In this two or more blocks of different sizes are prepared for testing.
→Pros being it provides better results and is less time taking, as we can stop once the relation is seen, con being it is difficult to perform.

Severe solar weather has the potential to cripple communication systems on earth.
Solar weather occurs when solar activity increases. Sudden bursts called Coronal Mass Ejections are the main culprits of <u>solar weather</u>. These CME's release bursts of plasma and charged particles straight towards the Earth. Once these particles impact the upper atmosphere they cause geomagnetic storms that interfere with radio signals and communication and possibly fry electronic devices.
Severe geomagnetic storms can cause devastation for Earth's communication network. These storms <u>interfere with radio communication, meaning that phone service, radio broadcasts, and even internet connection would be disabled</u>. Even worse, these storms can often damage electronics, specifically satellites. Damage to satellites can cause severe damage to modern-day infrastructure.
