In the recent Census, three percent of the U. S. population reported being of two or more races. However, the percent varies tremendously from state to state. Suppose that two random surveys are conducted. In the first random survey, out of 500 North Dakotans, only seventeen people reported being of two or more races. In the second random survey, out of 1,000 Nevadans, 9 people reported being of two or more races. Conduct a hypothesis test to determine if the population percents are the same for the two states or if the percent for North Dakota is statistically higher than Nevada. WHat is the p value for this question?

the two may have that, even a breakdown is probably offered

1/3 + 1/5 = 8/15.

step-by-step explanation:

hope it

the answer is 1/4

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
