Suppose the proportion of students retained by a university in 2020 is p and the proportion of students retained by the same university in 2021 is p. A study found a 90% confidence interval for p – p is (-0.0398, 0.0262). Give an interpretation of this confidence interval. a) "Loosely" stated, we are 90% confident that the proportion of students retained in 2020 is between 3.98% less and 2.62% more than the proportion of students retained in 2021. b) "Loosely" stated, we are 90% confident that the proportion of students retained in 2021 is between 3.98% less and 2.62% more than the proportion of students retained in 2020. c) We know that 90% of students retained in 2020 is between 3.98% less and 2.62% more than 2021. d) We know that 90% of students retained in 2021 is between 3.98% less and 2.62% more than 2020.

Question
Suppose the proportion of students retained by a university in 2020 is p and the proportion of students retained by the same university in 2021 is p. A study found a 90% confidence interval for p – p is (-0.0398, 0.0262). Give an interpretation of this confidence interval.
a) "Loosely" stated, we are 90% confident that the proportion of students retained in 2020 is between 3.98% less and 2.62% more than the proportion of students retained in 2021.
b) "Loosely" stated, we are 90% confident that the proportion of students retained in 2021 is between 3.98% less and 2.62% more than the proportion of students retained in 2020.
c) We know that 90% of students retained in 2020 is between 3.98% less and 2.62% more than 2021.
d) We know that 90% of students retained in 2021 is between 3.98% less and 2.62% more than 2020.
