The Answer Is B)He started programs to help the poor
If you have samples of n 1 equals 22 and n 2 equals 20, in performing the pooled-variance t test, you have 40 degrees of freedom.
The t-test method is a method where we analyze two sets of data which both these data are independent of each other. This pooled variance test helps us in getting the overall variance in both these different sample sets when we know that both the sample sets are almost equal.
To calculate degrees of freedom, we have the formula
df = n1 +n2 -2
According to the question, n1= 22 and n2= 20
Therefore, degree of freedom= 22 +20 -2 = 40
Hence, degree of freedom is 40.

Truth in Lending Act is the federal law that requires the cost of credit be disclosed to consumers in bold print on loan agreement
<h3><u>
Explanation:</u></h3>
The Truth in Lending Act (TILA) passed in 1968 to take care whether the consumers are treated fairly by revealing about the true cost of credit. The credit documents should be made very clear to the consumers. It does not place limitations on banks about how enough interest they may impose or whether they must give a loan.
This TILA statement includes annual percentage rate, schedule of payment and finance charges and the repayment within loan lifetime. Regulation Z is alternative name for Truth in Lending Act. Both the terms can be used in all aspects of lending and credit card purposes.
Answer:
John is participating in scaling; Jane is participating in a detection experiment question.
Explanation:
The experiment in which John is participating relates to the scaling question and the experiment in which Jane is participating relates to the detection question.
Scaling questions is a method used to construct understandings in order to assess a variable, situation, concern, relationship etc, it involved participant by asking them to perceive, described a variable based on a continuum i.e to rate, grade, usually based a scale of preference. John in the experiment was asked to determine how much brighter light has to be which is based on how he perceives the magnitude of the original light, the researcher is simply asking John to scale the light magnitude.
Detection questions are usually in an interrogative form used to exploring and searching for quality information; a technique that estimates detectability of the observer to accurately detect stimuli or a situation. Jane participating in an experiment was asked to determine how strong an odor has to be before she initially perceives the odor.
