Answer:
Confidence interval for the true mean number of reproductions per hour for the bacteria is (10.1,10.5).
Step-by-step explanation:
We are given the following in the question:
Population mean, μ = 10.3
Population standard deviation, σ = 2.1
Sample size, n = 728
Alpha, α = 0.01
Confidence interval:
Putting the values, we get,
Given:
Arc(AB) = 78 degrees
Measure of angle CMD = 106 degrees
To find:
The measure of arc CD.
Solution:
Secant intersection theorem: If two secant of a circle intersect each other inside the circle, then the intersection angle is the average of intercepted arcs.
Using secant intersection theorem, we get
Multiply both sides by 2.
Therefore, the measure of arc CD is 134 degrees and the correct option is C.
