A sleep researcher conducts an experiment where she randomly assigns 60 participants to receive one of three levels of sleep deprivation, sleep deprived for 24 hours (SD24), sleep deprived for 48 hours (SD48), and no sleep deprivation (SD0). After the experimental condition (sleep deprivation), the participants are given an auditory vigilance task and the correct percentages are calculated. The means for the three groups are SD0=76.6, SD24=61.8, SD48=48.6. The ANOVA F test had a p-value=.003. What is your statistical conclusion based on the ANOVA hypotheses?

a. The group with the most sleep deprivation had a lower mean than the other two groups.

b. The mean for the non-sleep deprived group performed significantly better than the other two groups.

c. The mean for the SD0 group was significantly greater than the mean for the SD24 group which was significantly greater than the mean for the SD48 group

d. The means for the three conditions were not all equal

d. vertex

step-by-step explanation:

whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

step-by-step explanation: so we look at the formula un = a + (n-1)d

un is the amount of seats

n is the nth term aka row number

a is the original sequence/row number

d is the difference between each term

so in this a=22 d=6 and n can remain as n because we are simply formjng a rule

lets put these in the equation

un=22+(n-1)(6)

this is your answer to part a

however

lets double check that this is correct, we'll try putting it into the second term

un=a+(n-1)d

u2=22+(2-1)(6)

u2=22+6

u2=28

as the question said the second row has 28 seats so now we know the formula we made is correct.

as for part b

un=a+(n-1)

its asking us to find a row with 100 seats.

remember un was the amount of seata so all we do is substitute this in.

un=100 a=22 d=6

un=a+(n-1)d

100=22+(n-1)(6)

so now we simplify to find n which is the row number.

100-22=22+(n-1)(6)-22

78=(n-1)(6)

78/6=(n-1)(6)/6

13=n-1

13+1=n-1+1

14=n

so now we know that in the 14th row there is 100 seats.

hope this and that you understood! its my first time using the app or anyone out on here : p its also me to revise so a bunch! ask more questions if you dont understand ☺
