Answer 1

  

GIVEN WEIGHTS OF 31 29 26 33 4028 30 AND 25 AT OK=0.05 TEST THAT THE POPULATION MEAN IS 35.

2- TAILED TEST OF MEAN WITH BOTH NEGATIVE AND POSITIVE CRITICAL VALUES

TESTING THAT A GASOLINE ADDITIVE INCREASE MILEAGE, WE COMPUTE MPG WITH ADDITIVE MINUS MPG WITH ADDITIVE FOR EACH CAR. IF THE MEAN OF THE DIFFERENCES IS POSITIVE ENOUGH ACTION WILL BE REQUIRED TO IMPLEMENT THE ADDITIVE.

1-TAILED TEST OF PAIRED DATA WITH POSITIVE CRITICAL VALUE

2-TAILED TEST OF MEANS OF 2 INDEPENDENT POPULATIONS.

TEST SIZE C BATTERY MEAN LIFE IS AT LEAST 25 HOURS

1-TAILED TEST OF MEAN WITH NEGATIVE CRITICAL VALUES
