Judge whether the following statements are true or false. Suppose a 95% confidence interval for the proportion of students who drink alcohol at TAMU is (0.61, 0.67).

a. The inference is that you can be 95% confident that the sample proportion falls between 0.61 and 0.67.

True or False

b. The inference is that there is a 95% chance that the population proportion falls between 0.61 and 0.67.

True or False

c. If we took many random samples of the same size, 95% of them would have a sample proportion between 0.61 and 0.67.

True or False

The answer is biodiversity resulting from new ancestors.

Answer: d. 39 cmin the diagram, the approximate length of the minor arc de is 39 centimetres.step-by-step explanation: the formula for the length of an arc in a circle is as displayed below.let the length of the minor arc de = xx = 2( pi )r × angle of sector / 360°from this, we will substitute the values given from the problem into the formula to obtain the length of the minor arc de.x = 2( pi )r × angle of sector / 360°r = radius = 25cmpi as an approximate value = 3.14angle of sector = 120°x = 2( 3.14 )( 25 ) × 120° / 360°x = 157 × 1 / 4x = 39.25x = 39 ( rounded to the nearest whole number as an approximate value )
