You are conducting a study to see if the probability of a true negative on a test for a certain cancer is significantly different from 0.88. Thus you are performing a two-tailed test. Your sample data produce the test statistic z = − 2.52 . Find the p-value accurate to 4 decimal places.

Find the probability that in a family of 4 children there will be
a) At least 1 girl
b) At least 1 boy and at least 1 girl
c) Out of 1500 families with 3 children each how many would you expect to have 1 or 2 girls.
Assume that the probability of a female birth is 1/2.

The probability of a man not hitting the target at a shooting range is .6. A success is defined as hitting the target. If he shoots 12 times, what is the probability that he misses the target just once? Do not use the table in the back of the textbook. (round to the ten thousandths place) ____
The probability of a man not hitting the target at a shooting range is .6. A success is defined as hitting the target. If he shoots 12 times, what is the probability that he does hit the target at most 3 times? Use the table in the back of the textbook. (do not round the value) ____
