Explain why no object that has mass can ever move at a speed equal to the speed of light.At what velocity do massless particles (e.g., photons) travel in vacuum?
P(Z > 1.9)
The probability that a standard normal random variable Z exceeds the value of 1.9, commonly used in statistical analysis to find tail probabilities.
Mean
The average of a set of numbers, calculated by dividing the sum of the values by their count.
Standard Deviation
A gauge that evaluates the breadth of fluctuation or spread of dataset values in relation to the central value.
Normally Distributed
This probability distribution is distinguished by its symmetric nature around the mean, showcasing higher frequencies of data points near the mean than those at greater distances.
