Sadistic Tendencies
You are captured by a Russian spy and tortured for information. Every time you fail to answer his question adequately, he plays the following game:
First, he draws a number randomly between 1 and 4. This becomes the comparison value. He then draws a number from between 0 and 4. If it is greater than or equal to the comparison value, you get a lash with a wet noodle, and he draws again. He continues this until he draws a number that is less than the comparison value, at which point he continues his interrogation. If he draws a 3 as the comparison value, what is the expected number of lashes you will receive for that question?
What is the expected number of lashes you will receive per question?
Test hypothesis that mean weight of 2 sheets are equal against alternative that they are not(suppose equal variances). Use α=0.05 and suppose equal variances. Determine the P value.

An election poll reported that a candidate has an approval rating of 54% with a margin of error of 4%. Construct a confidence interval for proportion of adults who approve of the candidate.
Consider a hypothesis test of H0: μ = 0 against H1: μ > 0 where μ is the mean percent change in total body bone mineral content of young women. The population standard deviation is σ = 2. The level of significance for the test is α = 0.05.
The calculated Z test statistic is a positive value that leads to a p-value of .045 for the test. If the significance level (α) is .01, the null hypothesis would be rejected.
