How does the estimate of the mean response used in the calculation of the confidence interval for the mean response compare to the predicted value used in the calculation of the prediction interval for an individual response? When you answer this question assume that the same estimated model is used in both cases and the same value of the explanatory variable is used to calculate the prediction interval and the confidence interval.
a. The estimate of the mean response is smaller than the predicted value for an individual response.
b. The estimate of the mean response is exactly that same as the predicted value for an individual response.
c. The estimate of the mean response is larger than the predicted value for an individual response.
d. We have no way to compare the relative magnitude of estimate of the mean response and the predicted value for an individual response.

i think it is 18

idk

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 ☺
