-14+3/2b-(1+2/8b), then take out the blanket become -14+3/2b-1-2/8b , get 5/4b-15=0 so 5/4b=15 ,get b=15×4÷5. b=12
Answer:
The test statistic for this test is 3.82.

The null hypothesis is:
The alternate hypotesis is:
Our test statistic is:
In which X is the sample mean,

11 mins
5:00
5:12
5:24
5:36
5:48
6:00
so the minutes go up in 12s meaning that their will be a bus at 7 and 8 so then you can work out
8:00
8:12
8:24
8:36
8:48
and 8:48 - 8:37 = 11 minutes waiting time
