A report in the college newsletter used the registrar's database for all the students in the school to look at majors and classes being taken this semester. The report includes the sentences:

According to the United States Census Bureau (2011 data), there are approximately 55,500,000 married couple households in the United State. Every married-couple household is classified into one of three categories:• both native which means that both spouses were born in the U.S.• both foreign which means that both spouses were born outside of the U.S.• one native, one foreign which means that one spouse was born in the U.S. and one was born outside of the U.S..If 79.5% of married couple households are both native and 13.2% are both foreign, then(a) what percentage of married couple households are one native, one foreign  % married couple households are one native, one foreign(b) how many married couple households are one native, one foreign?  married couple households are one native, one foreign

Like many parts of North America, the housing market in Halifax Regional Municipality (HRM) has been affected by COVID-19 and other global factors. In real estate sales, the house is listed for sale at a certain price (the Asking Price), and interested buyers will make offers on the house based on this Asking Price. If the demand for houses is low, buyers will typically offer less than the Asking Price; if the demand for houses is high (as it is in HRM now), buyers will typically offer more than the Asking Price. The final price a house sells for is the Selling Price. A statistics professor is trying to buy a house in HRM. Because many houses sell for more than the Asking Price, the professor wants to use statistics to inform the price they offer on houses. (The professor wants to offer enough money to win the house but not pay much more than other buyers were willing to offer) The professor wants to study the Amount Over Asking (AOA) for each house: the amount of money a house sells…

I conduct an online study to determine whether rewards reduce procrastination. All participants are asked to complete a task sometime before a deadline (10 days from now). The computer randomly assigns participants to one of three groups, and emails them their instructions; one group receives a reward as soon as they do the task (contingent reward); a second group receives rewards as soon as they finish the task as long as it is before the deadline (non-contingent reward) and the third group does not receive rewards at all (no reward). Three participants in the no reward condition do not complete the task, and so are dropped from analyses. The dependent variable is the amount of time (in days) it takes participants to complete the task. The JAMOVI output is attached. Post-hoc Tukey tests show that...

As you read about each​ study, (a) classify the type of research that it​ reflects, and​ (b) identify the kinds of conclusions that might reasonably be drawn from the results. An educational psychologist videotapes 20 high school history teachers in action for a period of 4 weeks. He then codes every teacher statement as belonging to one of three​ categories: whether it​ (a) presents new​ information, (b) asks a​ question, or​ (c) gives instructions. He summarizes this information and compares the amount of teacher questioning to the​ students' scores on a​ district-wide history achievement test given later in the year. The researcher finds that when teachers ask a lot of questions in​ class, students are more likely to score at high levels on the achievement test. ​(a) Classify the research as one of the​ following:   ​Quantitative/descriptive   ​Quantitative/correlational   ​Quantitative/experimental   ​Quantitative/quasi-experimental   Qualitative   Mixed​ methods, and…
