1. Suppose that a television news program conducts a call-in poll about a proposed city ban on
handgun ownership, with the result that 1921 of 2372 calls oppose the ban. Suppose further that
the news anchors make the following announcement: "81% of our sample opposed the ban, and
we can be 95% confident that the true proportion of citizens who oppose a handgun ban is
within 1.6% of the sample result."
a. Explain how the station calculated the 81% and 1.6% figures that it cites. (4 pts)
b. While their calculations are correct, the station has a major flaw in its process making the
conclusion invalid. Identify the flaw. (1 pts)

c.35

step-by-step explanation:

8+13=21

21+8=29

29+6=35

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 ☺
