A Biomedical engineer is measuring how much current is needed to stimulate the nerve of a rat to create a muscle function. He is measuring 5 rats and wants to evaluate if less current is needed to stimulate a young animal compared to an old animal. The mean of the current to stimulate young animals is 4.6mA. Meuasrements from trials on Old Rats: 6, 6, 12, 7, 8 (in mA) Can the engineer conclude that old rats need more current?

The trunk diameter, in centimeters,  of a certain variety of pine tree is represented by X~N(150, 30).  What is the 75th percentile of trunk diameters?  Round to two decimal places.

I need help with where do I start learning statistics since I have never taken a course before. I am taking Data Analysis SOCI 253 this Spring Semester

How would I identify the p-value?
