Suppose an airline claims that its flights are consistently on time with an average delay of at most 15 minutes.

it claims that the average delay is so consistent that the variance is no more than 150 minutes. doubting the consistency part of the claim, a disgruntled traveler calculates the delays for his next 25 flights.

the average delay for those 25 flights is 22 minutes with a standard deviation of 15 minutes.

graph the situation. label and scale the horizontal axis. mark the mean and test statistic. shade the p-value.

option c) graph of line going through 1, 4 and 3, 10

step-by-step explanation:

let y equal to margo's coin collection

let x equal to number of years

at the begining x=0, y=1 → point=(x,y)→point=(0,1)

she adds 3 coins per year, then y=1+3x

at x=1, y=1+3(1)=1+3→y=4→point=(x,y)→point=(1,4)

at x=3, y=1+3(3)=1+9→y=10→point=(x,y)→point=(3,10)

the graph of line going through (1, 4) and (3, 10), then the option c is the correct.

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
