Question
Rosa surveys 53 students at random to determine the proportion of students who have attended Mt. San Jacinto College for more than two years. Suppose that, in reality, 53% of students have attended for more than two years.
- How are the collection of all sample proportions of
samples of size 53 distributed?
N(, )
- What is the
probability that fewer than 48% of students in Rosa's sample have been enrolled for more than two years?
- List the zz-scores needed to calculate the result. If there is more than one zz-score, separate the values with a comma.
- There is a ------ chance that fewer than 48% of students in Rosa's sample have been enrolled for more than two years.
- What is the probability that more than 61% of students in Rosa's sample have been enrolled for more than two years?
- List the zz-scores needed to calculate the result. If there is more than one zz-score, separate the values with a comma.
- There is a -------- chance that more than 61% of students in Rosa's sample have been enrolled for more than two years.
- What is the probability that between 48% and 61% of students in Rosa's sample have been enrolled for more than two years?
- List the zz-scores needed to calculate the result. If there is more than one zz-score, separate the values with a comma.
- There is a ------ chance that between 48% and 61% of students in Rosa's sample have been enrolled for more than two years.

- Does playing Mozart for unborn babies result in having children with higher IQs? A psychologist obtains a random sample of 30 mothers in the first trimester of their pregnancy. The mothers are asked to play Mozart in the house at least 45 minutes each day until they give birth. We know that IQs are normally distributed with a mean of 100. A few years after their births the children were given an IQ test and the IQs of the 30 children in the study resulted in a sample mean of 104.2. Assume the population standard deviation for IQ of children is 15. Is there evidence that the children who listen to Mozart for at least 45 minutes each day during pregnancy have higher IQs at the 0.05 level of significance? Use the p-value approach. a. Define the parameter we are testing and setup a hypothesis test to see if the mean IQ of children who listened to Mozart at least 45 minutes a day during pregnancy is higher than the national mean of 100: b.
