37. A researcher believes that students who practice taking all of their regular tests on the computer will do better on the State's final exam which is on the computer than the students taking their
regular tests by paper and pencil. Which would be the null hypothesis?
a.
H: The average on the state exam of the students using paper and pencil tests is greater than or
equal to the average on the state exam of the students using computer tests.
b. H.: The average on the state exam of the students using paper and pencil tests is greater than the
average on the state exam of the students using computer tests.
c. H: The average on the state exam of the students using paper and pencil tests is less than or
equal to the average on the state exam of the students using computer tests.
d. H: The average on the state exam of the students using paper and pencil tests is less than the
average on the state exam of the students using computer tests.

Your friend uses c=50p to find the total cost, c, for the people, p, entering a local amusement park is the cost of admission proportional to the amount of people entering the amusement park? explain.

Amachine that produces a special type of transistor (a component of computers) has a 2% defective rate. the production is considered a random process where each transistor is independent of the others. (a) what is the probability that the 10th transistor produced is the first with a defect? (b) what is the probability that the machine produces no defective transistors in a batch of 100? (c) on average, how many transistors would you expect to be produced before the first with a defect? what is the standard deviation? (d) another machine that also produces transistors has a 5% defective rate where each transistor is produced independent of the others. on average how many transistors would you expect to be produced with this machine before the first with a defect? what is the standard deviation? (e) based on your answers to parts (c) and (d), how does increasing the probability of an event a↵ect the mean and standard deviation of the wait time until success?
