You and your friend decide throw a scrabble pizza party. You don't know how many pizzas to order, so you want to obtain an estimate of slices each person would eat. You perform a poll of ten randomly selected patrons to see how many slices they each ate. Their responses are Their responses are denoted Xi, i=1,...,10, and X=1/10 ∑10i=1Xi=4.3
s2=19∑10i=1(Xi−X)2=2.7

Assuming that the Xs are i. i.d. normal, construct a 95 confidence interval for the mean of the Xs.

1. Lower bound a
2. Upper bound b

How many patrons would you have had to poll to limit the width of the confidence interval to one slice?

step-by-step explanation:

answer: all of the odd numbers were opened

the first person was the one that was opening all of the lockers. since one is odd, this causes all of the odd number lockers to be opened in the end.

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
