ne the test statistic. Round to two decimal places as needed.
Angles in Circles
Angles within a circle are feasible to create with the help of different properties of the circle such as radii, tangents, and chords. The radius is the distance from the center of the circle to the circumference of the circle. A tangent is a line made perpendicular to the radius through its endpoint placed on the circle as well as the line drawn at right angles to a tangent across the point of contact when the circle passes through the center of the circle. The chord is a line segment with its endpoints on the circle. A secant line or secant is the infinite extension of the chord.
Arcs in Circles
A circular arc is the arc of a circle formed by two distinct points. It is a section or segment of the circumference of a circle. A straight line passing through the center connecting the two distinct ends of the arc is termed a semi-circular arc.
the answer is not 1.42, thank you for the help
![A researcher with the Department of Education followed a cohort of students who graduated from high school in a certain year, monitoring the progress the students
made toward completing a bachelor's degree. One aspect of his research was to determine whether students who first attended community college took longer to attain
a bachelor's degree than those who immediately attended and remained at a 4-year institution. The data in the table attached below summarize the results of his study.

L B.
The sampie sızes are not more tnan 5% Or tne popuiation.
Yc. The samples are independent.
O D. The population is given to be normally distributed.
YE. The sample sizes are large (both greater than or equal to 30).
c) Does the evidence suggest that community college transfer students take longer to attain a bachelor's degree? Use an a = 0.01 level of significance. Perform a
hypothesis test. Determine the null and alternative hypotheses.
O A. Ho: Hcommunity college <Hno transfer: H1: Hcommunity college > Hno transfer
O B. Ho: Hcommunity college> Hno transfer: H;: Hcommunity college <Hno transfer
CC. Họ: Hcommunity college = Hno transfer: H1: Hcommunity college >Hno transfer
O D. Ho: Hcommunity college = Hno transfer: H1: Hcommunity college <Hno transfer
Determine the test statistic.
