Assume a total current of 2 amperes flows in a circuit with three resistors. R1 has a value of 1400 ohms, R2 has a value of 200 ohms, and R3 has a value of 100 ohms, producing a total resistance of 80 ohms for the circuit. What is the amount of the current flow through resistor R1?

The File MT SAT Score.XLSX contains the results of a sample of 100 high school students SAT scores.  Use this data to perform a complete descriptive analysis including a histogram, boxplot and summary statistics associated with the observations.  Describe the shape spread and location of this data and discuss the presence of any possible outliers. Construct a normal probability plot for the SAT scores and discuss whether or not it would be reasonable to assume that this sample comes from a normally distributed population.  Construct a 95% interval estimate for the true mean SAT score for high school students taking this exam.  Include an interpretation for the interval you have constructed.

What does the terminology expressed as P(A|B) mean?

The advantage of using the interquartile range versus the range as a measure of variation is:

For two events A and B, P(A) = 0.8, P(B) = 0.2, and P(A ∩ B) = 0.16.  It follows that A and B are
