1) A machine produces metal rods used in an automobile sus-
pension system. A random sample of 8 rods is selected, and the diameter is
measured. The resulting data (in millimeters) are as follows :
8.24 8.25 8.20 8.23
8.21 8.26 8.26 8.28
Assume that the population is normally distributed.
(a) Can we reject the claim that the mean rod diameter is 8.25 mm at a level
of signicance of 5% ?
(i) Answer using a critical region.
(ii) Answer using a p-value.
(b) Calculate a 95% condence interval for the mean rod diameter. Does the
condence interval support the conclusion from part (a)
a. No. p is 0.389 (>0.05).
b. The confidence interval is (8.22, 8.26).

An automobile having a radio antenna 110 cm long travels at 90 km/h in a region where Earth magnetic field is?
55 Tesla. Find the maximum possible value of the induced emf? (This numerical related to Motional EMF)
The induced EMF is defined as Blv, when B,l and v are all perpendicular to each other. In this case they are. The field is in the North-South direction, the v(velocity of the car) is in the East-West direction and the length is in the up down direction.
B = 55 T
l = 110 cm = 1.1 m
v = 90 km/hr = 90000/3600 = 25 m/s
So, the induced EMF = 25*1.1*55=1512.5 V
{This is a very high difference indeed, but this is because you have mentioned the earth’s field as 55 T. It is ordinarily 5*10^-5 T}
