Continuous Probability Distributions

Probability distributions are of two types, which are continuous probability distributions and discrete probability distributions. A continuous probability distribution contains an infinite number of values. For example, if time is infinite: you could count from 0 to a trillion seconds, billion seconds, so on indefinitely. A discrete probability distribution consists of only a countable set of possible values.

Normal Distribution

Suppose we had to design a bathroom weighing scale, how would we decide what should be the range of the weighing machine? Would we take the highest recorded human weight in history and use that as the upper limit for our weighing scale? This may not be a great idea as the sensitivity of the scale would get reduced if the range is too large. At the same time, if we keep the upper limit too low, it may not be usable for a large percentage of the population!

Question

We want to investigate the correlation between
concentration of Se (Selenium) in the teeth and
its concentration in the liver in 20 Beluga
240
220
Whales.
We suspect that the higher the
concentration in the liver, the higher the
concentration in the teeth. A plot of the data is
given at right, and the following summary
statistics are given for these data:
200
180
160
x = 20.68 Sx
= 13.45
y = 156.60
Sy
= 36.06
140
Se = 31.25
Before actually computing its value (that is, by just
looking at the scatterplot), how do we know that
r > 0 (rather than r = 0 or r < 0)?
r =
0.54
120
10
20
30
40
Liver Se (ug/g dry wt)
Tooth Se (ng/g dry wt)

d) Estimate the approximate expected Tooth Se if Liver Se were 30.
e) Test the hypotheses Ho: B1 = 0, H4: B1 # 0 by finding a 95% confidence interval for B1.
