Fill in the blanks. the owner of get-a-away travel has recently surveyed a random sample of 208 customers to determine whether the mean age of the agency's customers is over 26. the appropriate hypotheses are upper h 0: muequals26, upper h subscript a baseline : mu greater than 26. if he concludes the mean age is over 26 when it is not, he makes a error. if he concludes the mean age is not over 26 when it is, he makes a error.

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 arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
