Some people say that more babies are born in September than in any other month. To test this claim, you take a simple random sample of 150 students at your school and find that 21 of them were born in September. You are interested in whether the proportion born in September is higher than 1/12-what you would expect if September was no different from any other month. Thus your null hypothesis is H0:p= 1/12. The P-value for your test is 0.0056. Which of the followingstatements best describes what the P-value measures?
|
|
The probability that September birthdays are no more common that any other month is 0.0056.
|
|
|
The probability that September birthdays are more common is 0.0056
|
|
|
The probability that the proportion of September birthdays in the population is not equal to 1/12 is 0.0056
|
|
|
0.0056 is the probability of getting a sample with a proportion of September birthdays this far or farther above 1/12 if the true proportion is 1/12
|
|
|
0.0056 is the probability of getting a sample with a proportion of September birthdays this close to 1/12 if the true proportion is not 1/12
