Gary bought a gift for his friend and Is having It gift wrapped at the store. The wrapping paper comes In four patterns: floral, spiral, cartoon character, and plain. For ribbon, he can choose between red, blue, or green. If Gary randomly selects a paper pattern and a ribbon color, what Is the probability that he chooses spiral-patterned paper and a green ribbon?

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 IQ score of students in a large statistics class is less than 130. A simple random sample of the students has a mean IQ score of 107.9. 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 not 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 not unusual if the claim is true. The sample is…

A pharmaceutical company receives large shipments of ibuprofen tablets and uses sampling plan to accept the shipmemts. They randomly select and test 27 tablets, and accept the entire batch if there is at most one tablet that does not meet the required specifications.Suppose a particular shipment of ibuprofen tablets has a 4% rate of defects. What is the probability that this whole shipment will be accepted?

A bank has recently acquired a new branch and thus has customers in this new territory. They are interested in the default rate in their new territory. They wish to test the hypothesis that the default rate is different from their current customer base. The sample 200 files in area A, their current customers, and find that 20 have defaulted. In area B, the new customers, another sample of 200 files shows 12 have defaulted on their loans. At a 10% level of significance can we accept/reject the null hypothesis H0 : pA = pB against the alternative hypothesis Ha : pA ≠ pB? a. Hull hypothesis CAN NOT be rejected at 10% confidence level. b. Hull hypothesis CAN be rejected at 10% confidence level.

researcher is creating a new treatment protocol for Myelodysplastic Syndrome (MDS), a form of preleukemia. Following the old treatment protocol, 28% of patients with MDS will develop leukemia within 5 years of MDS diagnosis. He believes his new treatment protocol will lead to fewer MDS patients developing leukemia. He takes a random sample of 100 individuals on his new treatment protocol. Of these 100 individuals, 20 develop leukemia within 5 years of MDS diagnosis. Conduct a hypothesis test at the 10% level to test this claim that his new treatment protocol will lead to fewer MDS patients developing leukemia. What are the hypotheses? a. H0: p = 0.28; HA: p < 0.28 b. H0: p > 0.28; HA: p < 0.28 c. H0: p = 0.28; HA: p = 0.20 d. H0: p̂ = 0.28; HA: p̂ < 0.28 e. H0: μ = 28; HA: μ ≠ 28
