An efficacy study was conducted for the drug pamidronate in patients with stage III multiple myeloma and at least one lytic lesion. In this randomized clinical trial, patients were assigned at random to receive either pamidronate or placebo. One endpoint reported was the occurrence of any skeletal events after 9 cycles of treatment or non-occurrence.

A sample space contains number of pins of a 12-pin IC that are not functioning. Event ‘unacceptable’ takes place when more than or equal to half the pins are not functioning. Event ‘acceptable’ takes place when more than 10 pins are functioning. (note: write down the accurate sample space for the experiment first. Check again if the outcomes in sample space represent all possibilities of observations for this experiment) Identify outcomes contained in each event. Identify if the two events are independent.

What is the probability of flipping a coin three times and getting two heads and one tail, assuming the coin is fair? How does this probability change if the coin is biased towards heads? Furthermore, what is the expected number of heads that would be flipped in five coin tosses?
The National Claims History (NCH) contains records for 999,645 Medicare patients who were discharged from acute care hospitals in October 2008. The Department of Health and Human Services performed a detailed audit of adverse medical events on a random sample of 780 drawn at random without replacement by assigning a random number to each patient on the list and then choosing random integers between 1 and 999,645. (a) What kind of sample is this (random, systematic, stratified, cluster)? (b) Is this population effectively infinite?
Two fair six-sided dice are rolled. Let A = the event that the dice add to 7, and let C = the event that the dice show the same number. Find P(CIA') and P(C'IA'). P(CIA') = (Simplify your answer.) P(C'A') = (Simplify your answer.)

NOTE: Please show me STEPS how to resolve these two questions in "STATCRUNCH" Question1) Make a decision about the given claim. Use only the rare event rule, and make subjective estimates to determine whether events are likely. For example, if the claim is that a coin favors heads and sample results consist of 11 heads in 20 flips, conclude that there is not sufficient evidence to support the claim that the coin favors heads (because it is easy to get 11 heads in 20 flips by chance with a fair coin). Claim: The mean of students in a large class is than . A simple random sample of the students has a mean of 97.3. Choose the correct answer below: A. The sample is not unusual if the claim is true. The sample is unusual if the claim is false. Therefore, there is sufficient evidence to support the claim. B. The sample is unusual if the claim is true. The sample is not unusual if the claim is false. Therefore, there is not sufficient evidence to support the claim. C. The sample is…
Suppose a lot of 25 machine parts is delivered and that a part is considered acceptable only if it passes a tolerance test. Suppose further we sample 10 parts and find that none are defective. What is the probability of this event if there are 6 defective parts, that is, parts that do not pass a tolerance test, in a lot of 25?
