Heights of males are norm. dist. w/ u=180cm and o^2=16cm^2 while female heights have u=170cm and o^2=25cm^2. a)random male and female selected. What is the probability that the male is >5 cm taller? What is the distribution avg of the 2 heights? b)what is...

Given a Helium-Neon laser-based fiber optic Doppler probe at an angle of 60¡C with a blood vessel that registers a frequency shift of 63KHz, what is the velocity of the blood? Is this a reasonable number from a physiologic point of view when compared to t...

For liver tissue irradiated by the pulsed Ho:YAG laser, determine the exposure duration which the equation for heat conduction may be ignored. Assume the absorption coefficient at the Ho:YAG laser wavelength is 30cm-1 and assume the thermal diffusivity of...

The standard deviation of all possible sample proportions increases as the sample size increases - TRUE OR FALSE

The sampling distribution of x bar must be a normal distribution with a mean 0 and standard deviation 1. true or false

A 82% confidence interval for a sampling distribution with a mean of 100, a sample standard deviation of 24 and a sample size of 36 will be based on a á= ______ and a corresponding Zá of ____ .18 and .47 .18 and .915. .09 and .23 .09 and 1.34

What is the p-value when we test H0 : µ = 10 versus Ha: µ < 10 and have a calculated test statistic Z = -2.41 (ó is known) .008 -.008 .016 .4920 -.4920

The Smith family made an $800 down payment and pays $75 a month for new furniture. At the same time the Cooper family made a $500 down payment and pays $95 a month for their new furniture. How many months until the amounts they have paid will be equal? Pl...

Suppose that X is an exponential random variable with parameter (and mean) equal to 1. Find the MAP estimate of X , given that there were exactly 5 blue flashes.

Suppose that X is equal to either 1 or 2, with equal probability. Write down an expression for the probability that there were exactly 3 arrivals during the time interval [0,2] .

I know it's just a linear dimension, I'm just assuming it's my prof's mistake (as he squared the sd to get variance). I simply copied directly from the paper.
