Astudy finds that college students found it unpleasant to sit alone and think.1 the same article describes a second study in which college students appear to prefer receiving an electric shock to sitting in solitude. the article states that "when asked to spend 15 minutes in solitary thought, 12 of 18 men and 6 of 24 women voluntarily gave themselves at least one electric shock." use this information to estimate the difference between men and women in the proportion preferring pain over solitude. the standard error of the estimate is 0.154.let group 1 be men and group 2 be women. give notation for the quantity that is being estimated. link to text (b) give notation for the quantity that gives the best estimate. link to text (c) give the value for the quantity that gives the best estimate. round your answer to three decimal places. best estimate = the absolute tolerance is +/-0.01link to text (d) give a 95% confidence interval for the quantity being estimated. round your answers to three decimal places. the interval is to .link to text (e) is "no difference" between males and females a plausible value for the difference in proportions? yesno

lockers 1, 4, 9, 16, 25, 40, and 49 are open

i ran through it by the other answer is wrong

1. 3. can also be expressed as (22/7)

2. -4.5

3. 3.6

happy to

pls mark as brainliest

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 ☺

if you would like with a question it is easy to get an answer by including some or multi choice options
