Please criticize the following statement regarding the interpretation of a confidence interval: Results for a 95% Confidence Interval for estimating the population mean: 74.1< Mean< 83.1 " After looking at the above results we can conclude that there is a 95% chance that the confidence interval contains the true mean of the population" Is the above statement correct? Why? If it is not correct how can we re-state the conclusion in order to interpret correctly the above confidence interval? I recommend reading from your book or you can also search in the Internet for some help regarding the correct interpretation of a confidence interval.

The statement is correct .

Step-by-step explanation: When constructing a confidence interval (95%) for this question, the interval we get as our answer simply implies that we are 95% sure that our population mean is within the interval value that we just calculated

Because it says that BE is a diameter, and that the distance around half of the circle is 180 degrees, you can set 7x+ 5x+12=180, so you know that 12x equals 168. So, x equals 14. 5 times 14 is 70, plus 12 is 82. Subtract 82 from 180, to get 98. Divide that by2 to get 49, because those two arcs are congruent. Because central angles are congruent to the measures of the arcs that they intersect, the answer is 49 degrees.
