Determine if the following is an example of descriptive or inferential statistics. A hospital administrator wants to see if fewer mistakes are made if nurses are forced to take frequent
breaks. After observing a sample of 300 nurses who were not forced to take frequent breaks and 400
who were forced to take frequent breaks, it was clear from the data that implementing a policy to
force nurses to take frequent breaks will decrease the average number of mistakes.

john earns $14.00 for two hours of work.

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

the answer is 13 cm
