Researchers determined that 60 puffs tissues is the average number of tissues used during a cold. suppose a random sample of 100 puffs users yielded the following data on the number of tissues used during a cold: x = 52 and s = 22. suppose the alternative we wanted to test was h: u< 60. the correct rejection region for a = 0.05 is: reject h, ift < -1.9842. o reject h, ift< -1.6604. o reject h, if: > 1.6604. "o reject h, if > 1.9842 or z< -1.9842.

step-by-step explanation:

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
