Complete Question

You construct a 95% confidence interval for a population mean using a random sample. The confidence interval is

24.9<μ<31.5  . Is the probability that  μ  is in this interval 0.95? Explain.

Generally the probability that the true mean will be within this confidence interval is not 0.95. What this confidence interval tell us is that there is a 95% confidence that the true mean of this population lies within this interval.  

Step-by-step explanation:

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
