2-Proportion Test

In a 2-proportion test, two separate proportions are measured at the same time, and their similarity is evaluated. It is also known as a 2-proportion z-test, and a comparison of two different proportions is done in this method.

2) A company was examining the perception of sports fans in a specific region and outside of that region to see if people viewed a specific team favorable or unfavorable. It was previously determined that given a person was from the region the probability they considered the team favorable was 0.7, and given that the person was not from the region, the probability they considered the team unfavorable was 0.28. Consider a collection of 35 people were surveyed, where 28 were from the region, and 7 people were from outside the region. a) Given that a randomly selected response from the sample was favorable, what is the probability they were from the region? b) Given that a randomly selected response from the sample was not favorable, what is the probability they were from the region?

(Not graded, practice problems only.) When purchasing bulk orders of batteries, a toy manufacturer uses this acceptance sampling plan: Randomly select and test 39 batteries and determine whether each is within specifications. The entire shipment is accepted if at most 3 batteries do not meet specifications. A shipment contains 3000 batteries, and 2% of them do not meet specifications. What is the probability that this whole shipment will be accepted? Will almost all such shipments be accepted, or will many be rejected? The probability that this whole shipment will be accepted is______ The company will accept ____% of the shipments and will reject ____% of the shipments
Use the given probability value to determine whether the sample results could easily occur by chance, then form a conclusion. A study of the effect of seatbelt use in head-on passenger car collisions found that drivers using a seatbelt had a 64.1% survival rate, while drivers not using a seatbelt had a 41.5% survival rate. If seatbelts have no effect on survival rate, there is less than a 0.0001 chance of getting these results. What do you conclude? The probability shows that the sample results ▼ could could not have easily occurred by chance. It appears that there ▼ is is not sufficient evidence to conclude that seatbelts do have an effect on survival rate.
