Three students, Jim, Joan, and Jethroe are registered for the same class and attend independently to each other, Jim 95.7% of the time, Joan 92.3% of the time, and Jethroe 82.8% of the time. What is the probability that on any given day:
a) None of them will be in class?
b) At least two of them will not be in class?
A null hypothesis is that the average pulse rate of adults is 70. For a sample of 64 adults, the average pulse rate is 71.8. A significance test is done and the p-value is 0.02. What is the most appropriate conclusion based on α of 0.05?

Carleton Chemical claims that they can produce more than 800 tons of meladone on average per week. A random sample of 36 weeks of production yields the following results.
State a conclusion about the null hypothesis-reject Ho or fail to reject Ho. State a final conclusion-non-technical that addresses the original claim.
A hypothesis test for a population proportion ρ is given below: Ho: ρ = 0.10 Ha: ρ ≠ 0.10
Suppose that you do a test for H0: μ = 6 against HA: μ &neq; 6 you obtain a sample mean of 6.5 and the test gives you a a p-value of 6%. We want to connect the p-value to the confidence interval for the mean.
