An exercise scientist wants to show that 20 year old women athletes have lower blood pressure than the general population of 20 year old women. It is known that, the systolic blood pressure
of 20 year old women has a mean of 120.
Which of the following pairs represent appropriate hypotheses for this problem?
a. Hu=120 vs. Hul> 120
C. Horu=120 vs. H: 120
b. Hofu 120 vs. He:u=120
d. Hou 120 vs. Hu=120
Ο Α
(1) В
D

the answer is the option b

the range is all real numbers

step-by-step explanation:

we know that

the absolute value parent function is equal to

see the attached figure to better understand the problem

so

a. it is v-shaped > is true

b. the range is all real numbers > is not true

because the range is the > [0,∞)

all real numbers greater than or equal to zero

c. it goes through the origin > is true

d. the domain is all real numbers > is true

step-by-step explanation:

amount of oatypop that contains the prize = 40%

amount   of oatypop which doesn't contain the prize = (100-40)=60%

probability that hannah will win a prize

    = s +f s +f f s+ff   f s+ff f f s+ infinity.where f= failure,s= success

=   or 60%

probability that hannah only has to buy 3 or less boxes before getting a prize= (s) and ( f s) and (ff s) and (f f f s)

        = = 87.04 %  

step-by-step explanation:

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
