Some of my best students don't demonstrate their best work on online tests. Here are some tips and strategies to help you show that computer what's going on upstairs.

When a vertical beam of light passes through a transparent medium, the rate at which its intensity I decreases is proportional to I(t), where t represents the thickness of the medium (in feet). In... more

The population of a community is known to increase at a rate proportional to the number of people present at time t. If an initial population P0 has doubled in 6 years, how long will it take to... more

Suppose that A is a 2 × 2 Wishart distributed random matrix (i.e., A ∼ Wp (n, Σ) with p = 2 and n ≥ 2). Prove using elementary methods that det(A) is distributed like det(Σ) times two independent... more

This account is under my email. Is there anyway to add my daughter’s so she get email messages also and I don’t have to always forward them?

Fisher's Limiting Spectral Distribution Fs,t(x) = (1-t/2pi*(s+tx))sqrt((b-x)(x-a). where a is less than equal to x and x is less than equal to b. a = (1-h)^2/(t-t^2), b= (1+h)^2/(1-t)^2 , h=... more

A past study on the reaction time of children with cerebral palsy reports a mean of 1.6 seconds on a particular task. Aresearcher believes that the mean reaction time can be reduced by using a... more

Assume that the wavelengths of photosynthetically active radiations (PAR) are uniformly distributed at integer nanometers in the red spectrum from 640 to 670nm.What is the variance of the... more

You draw a card from a deck If you get a red card ou win nothing. If you get a spade you win $5. If you draw a club you win $10 plus an extra $20 for the ace of clubs. Create a probablity model for... more

Hi, I need an idea for a creative project for my statistics class, It should be a simple one. I have some statistical definitions and I have to put them in a creative way! Thank you,
