A study of 50 randomly selected students from a particular college who did not go to the campus Learning Center for statistics tutoring had a mean overall grade (at the end of the semester) of 68.41% with a standard deviation of 9.60%. The same study also found that 48 randomly selected students who did take advantage of the tutoring at the campus Learning Center had a mean overall grade of 79.25% with a standard deviation of 8.71%. The standard deviation for both populations (students who did not use the Learning Center’s tutoring, and those students who did use it) is assumed to be equal. Construct a 99% confidence interval for the difference of the mean overall grade of students who did not use the Learning Center minus the mean overall grade of students who did use it.
a. (-15.70%, -5.997%)
b. (-15.71%, -5.968%)

. Suppose that the Vermont government needs to collect $10 from each adult who lives in Vermont and
there are two alternative ways to collect the $10 from each adult: (a) $10 of income tax from each
adult and (b) a 2% sales tax on food for the first $500 spent on food (2% of $500 is equal to $10 and
we assume each adult spends at least $500 on food per year in Vermont).
3) Is the response from your friends consistent with the lump-sum principle? If any of them selected
(b) or (c), explain the possible reasons for the inconsistency with the principle.

1-) A researcher who thinks that Sanav anxiety reads
the effect on the scores obtained from the success tests, wants to
decrease the anxiety levels with a therapy to be applied to
students. In this regard, students want to have an idea about the
effectiveness of the method applied by measuring their anxiety
levels before and after therapy. The lowest score on the scale of
fight is 10, the highest score. 10 full points show the point where
the loss is highest. Pre-therapy anxiety scores of eight students
were 5, 7, 8, 9, 0, 1,2,4; The therapy sonrass anxiety scores were
determined as 3, 2, 7.8, 2, 1.3.3, respectively.
a. )According to both cases, we dry the research hypothesis and
test it. We comment on the effectiveness of therapy.
b.) We calculate and interpret confidence intervals and effect size
values.

Mrs. A. is an 84-year-old woman who was recently discharged from the hospital with a diagnosis that includes an exacerbation of congestive heart failure (CHF). She also has diabetes and hypertension. Mrs. A. was discharged from the hospital on multiple medications and lives alone. Home care services were initiated with skilled nursing care visits, some home health aide support, and orders to include daily telemonitoring of her vital signs. The telehealth device will remotely monitor Mrs. A.’s blood pressure, heart rate, oxygen saturation, and weight. In addition, the patient will answer customized questions about her disease on a daily basis. This information will then be transmitted daily to the home care agency, where the telenurse can determine appropriate clinical actions based on the data trends and preset baseline alerts that indicate when set parameters have been exceeded.
