The polling organization ipsos conducted telephone surveys in march of 2004, 2005 and 2006. in each year, 1001 people age 18 or older were asked about whether they planned to use a credit card to pay federal income taxes that year. the data are given in the accompanying table. is there evidence that the proportion falling in the three credit card response categories is not the same for all three years? test the relevant hypotheses using a .05 significance level.

the answer will be b x² +x-1

step-by-step explanation:

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

multiply then divide
