The water diet requires you to drink two cups of water every half hour from the time you get up until you go to bed, but otherwise allows you to eat whatever you like. Four adult volunteers agree to test the diet. They are weighed prior to beginning the diet and after six weeks on the diet. The weights (in pounds) are Subject
A
B
C
D
Weight before diet
180
125
240
150
Weight after 6 weeks
170
130
215
152

What would a Type II error be for this test of the water diet?
a
Concluding that the diet leads to weight loss when it doesn’t.
b
Concluding that the diet leads to weight loss when it really does.
c
Not concluding that the diet leads to weight loss when it does.
d
Not concluding that the diet leads to weight loss when it really doesn’t.
e
Drawing a conclusion from this test when the Normality condition has not been satisfied.

The angle of a triangle are given as 6x,(x-3), and (3x+7). find x then find the measures of the angles

Aprisoner is trapped in a cell containing three doors. the first door leads to a tunnel that returns him to his cell after two days of travel. the second leads to a tunnel that returns him to his cell after three days of travel. the third door leads immediately to freedom. (a) assuming that the prisoner will always select doors 1, 2 and 3 with probabili- ties 0.5,0.3,0.2 (respectively), what is the expected number of days until he reaches freedom? (b) assuming that the prisoner is always equally likely to choose among those doors that he has not used, what is the expected number of days until he reaches freedom? (in this version, if the prisoner initially tries door 1, for example, then when he returns to the cell, he will now select only from doors 2 and 3.) (c) for parts (a) and (b), find the variance of the number of days until the prisoner reaches freedom. hint for part (b): define ni to be the number of additional days the prisoner spends after initially choosing door i and returning to his cell.
