Concept explainers

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 average number of accidents at controlled intersections per year is 5. Is this average more for
intersections with cameras installed? The 60 randomly observed intersections with cameras installed had an
average of 5.3 accidents per year and the standard deviation was 0.82. What can be conduded at the a =
0.01 level of significance?
a. For this study, we should use Select an answer
b. The null and alternative hypotheses would be:
Ho: ? v| Select an answer
H: ? v Select an answer
c. The test statistic ? =
(please show your answer to 3 decimal places.)
d. The p-value =
(Please show your answer to 4 decimal places.)
e. The p-value is ? va
f. Based on this, we should Select an answer
g. Thus, the final condusion is that ...
the null hypothesis.
O The data suggest that the sample mean is not significantly more than 5 at a = 0.01, so there is
statistically insignificant evidence to condude that the sample mean number of accidents per
year at intersections with cameras installed is more than 5.3 accidents.
O The data suggest that the population mean is not significantly more than 5 at a = 0.01, so there
is statistically insignificant evidence to condude that the population mean number of accidents
per year at intersections with cameras installed is more than 5 accidents.
O The data suggest that the populaton mean is significantly more than 5 at a = 0.01, so there is
statistically significant evidence to condude that the population mean number of accidents per
year at intersections with cameras installed is more than 5 accidents.

h. Interpret the p-value in the context of the study.
O If the population mean number of accidents per year at intersections with cameras installed is 5
and if another 60 intersections with cameras installed are observed then there would be a
0.31428259% chance that the population mean number of accidents per year at intersections with
cameras installed would be greater than 5.
O There is a 0.31428259% chance of a Type I error.
O If the population mean number of accidents per year at intersections with cameras installed is 5
and if another 60 intersections with cameras installed are observed then there would be a
0.31428259% chance that the sample mean for these 60 intersections with cameras installed
would be greater than 5.3.
O There is a 0.31428259% chance that the population mean number of accidents per year at
intersections with cameras installed is greater than 5.
i. Interpret the level of significance in the context of the study.
O There is a 1% chance that the population mean number of accidents per year at intersections
with cameras installed is more than 5.
O If the population mean number of accidents per year at intersections with cameras installed is 5
and if another 60 intersections with cameras installed are observed then there would be a 1%
chance that we would end up falsely condu ding that the population mean number of accidents
per year at intersections with cameras installed is more than 5.
O If the population population mean number of accidents per year at intersections with cameras
installed is more than 5 and if another 60 intersections with cameras installed are observed then
there would be a 1% chance that we would end up falsely conduding that the population mean
number of accidents per year at intersections with cameras installed is equal to 5.
O There is a 1% chance that you will get in a car accident, so please wear a seat belt.
