How many randomly selected air passengers must you survey? Assume you want to be 90% confident that the sample percentage is within 2.5 percentage points of the true population percentage. Completed parts a and b below. A.) assume that nothing is known about the percentage of passengers who prefer aisle seats. N= ____ (round up to the nearest integer) B.) assume that a prior survey suggest that about 35% of air passengers prefer an aisle seat. N=____ (round up to the nearest integer)I need answer for letter d. The last part. Thank you!

He chooses a marble from a bag of three marbles: one is blue, one is red, and one is green. Based on the marble he chooses, he completes a certain number of push-ups, as shown below. Marble Number of push-ups blue red green 10 Consider choosing a marble like sampling from a population. (The population mean of the number of push-ups is u=9.00 and the population standard deyiation is o =0.82.) (a) Suppose a sample of size 2 is randomly selected from the population, with replacement, as follows. One marble is randomly chosen, the number of push- ups is completed, and the marble is put back into the bag. Then for a second time a marble is randomly chosen and the number of push-ups is completed. There are 9 possible samples. The numbers of push-ups for several of the possible samples have been listed in the table below. Enter the numbers of push-ups for the remaining possible samples. When you are done, select "Compute". In the "Sample mean, x" column,…= 12,000 and p = 0.71. A random sample of 902 elements selected from this population gave p 0.61. Find For a population, N the sampling error. Enter the exact answer. sampling error =
