Question

about 5% of employed adults in the united states had multiple jobs. a random sample of 68 employed adults is chosen. use the ti 84 calculator as needed.

a) is it appropriate to use the normal approximation to find the probability that less than 6.5% of the individuals in the sample hold multiple jobs? if so, find the probability.

it is or it is not appropriate to use the normal curve, since np is:

the inequality sign is:

b) a new sample of 336 employed adults is chosen. Find the probability that less than 6.5% of the individuals in this sample hold multiple jobs. round the answer to at least four decimal places.

the probability that less than 6.5% of the individuals in this sample hold multiple jobs is:

c)the probability that more than 6.5% of individuals in the sample of 336 hold multiple jobs is:

d) find the probability that the proportion of individuals in the sample of 336 who hold multiple jobs is between 0.054 and 0.10. round your answer to at least four decimal places.

the probability that the proportion of individuals in the sample of 336 hold multiple jobs is between 0.054 and 0.10 is:

e)would it be unusual if less than 2.5% of the individuals in the sample of 336 held multiple jobs?

it would or would not be unusual if less than 2.5% of the individuals in the sample of 336 held multiple jobs, since the probability is:

Answer 1

It is not appropriate to use the normal curve, since np is lerss than 5.

It would be unusual if less than 2.5% of the individuals in the sample of 336 held multiple jobs, since the probability is less than 0.05.
