Many questions in research can be expressed as two competing statements about the population parameter. These two statements are called the null and the alternative hypotheses. Usually, the researcher hopes the sample evidence will be in favor of the alternative hypothesis, the new theory. It is important to be able to state the theories that are being put to a test.
For each scenario below, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem.
1. According to the World Bank, 10.7 percent of the world's population lived in poverty in 2013. Researchers wonder if this rate has changed since then (was the rate different in 2022 compared to 2013?).For this scenario, write out the hypotheses to be put to the test and define the parameter of interest in context of the problem. H0:Ha: The parameter p represents ___(provide appropriate definition in context)________

The national average SAT score is roughly 1500. We
would like to see if the high school seniors who apply
to Duke have higher than average SAT scores. We
randomly sample 100 applicants' files and record
their SAT scores. Which of the following is the
correct set of hypotheses for this research question?
H0: μ 2 150; HA : μ H National; HA: H Duke H National
Ho: H s 1500; HẠ: µ > 1500
Но: и3 1500; НА: 1500
A researcher thinks that if expectant mothers use vitamins, the birth weight of the babies will increase. The average birth weight of the population is 3.9 kgs. What is the alternative hypothesis?
a. Ha: ? > 3.9
b. Ha: ? < 3.9
c. Ha: ? = 3.9
d. Ha: ? ≠ 3.9

- A school psychologist is interested in the efficiency of administration for a new intelligence test for children. In the past, the Wechsler Intelligence Scale for Children (WISC) was used. Thirty sixth grade children are given the new test to see whether the old intelligence test or the new intelligence test is easier to administer. Is this a non-directional or directional hypothesis? How do you know?arrow_forwardQuestion 4: give the conclusion.arrow_forwardWhich hypothesis represents the statement of "no change" (or "no affect/difference"), that we assume to be true?

- Comparing data from Web-surveys to paper-pencil surveys, which of the following is true: Question 8 options: Data from paper-pencil surveys need to be checked for editing. Data from paper-pencil surveys need to be coded. Data from Web-surveys need to be coded. a & b are true all these statements are truearrow_forwardQuestion 2. In a given university, some scholarships were offered to students. This depends on the GPA the student gets and having his/her application submitted on time. 40.1% of the students applying have the required GPA. Given that the student has the required GPA, 77.56% of the students received a scholarship. And given that the student doesn't have the required GPA, 6.51% of them received a scholarship. Knowing that a student got a scholarship and have the required GPA, 96.46% of them had applied before the due date. On the other hand, the probability that the student submitted his application on time knowing that he didn't have the required GPA and he didn't get a scholarship was 1.79%. Given that the student didn't get a scholarship and had the required GPA, 2.22% of the applications were submitted on time. Of all applications, 3.4% of the applications were submitted on time, the student didn't have the required GPA and the student got a scholarship.arrow_forwardIdentify the null and alternative hypothesis for the given scenario: Students earning a Master's degrees takes on average 4.9 years to graduate. The dean of a major university claims the Master students at his university graduate earlier than 4.9 years. H.: 4.9 Ha: 4.9arrow_forward
