GIVEN QUESTION:THE PERFORMANCE OF A COMPUTER IS OBSERVED OVER A PERIOD OF 2 YEARS TO CHECK THE CLAIM THAT THE PROBABILITY IS 0.20 THAT IS DRAWN TIME WILL EXCEED 5 HOURS IN ANY GIVEN WEEK. TESTING THE NULL HYPOTHESIS μ=0.20 AGAINST THE ALTERNATE HYPOTHESIS μ=0.20, WHAT CAN WE CONCLUDE AT LEVEL OF SIGNIFICANCE α=0.05 IF THERE WERE ONLY 11 WEEKS IN WHICH THE DRAWN TIME OF THE COMPUTER EXCEED 5 HOURS? (answer in value )IT IS CLAIMED THAT A RANDOM SAMPLE OF 49 TYRES IS A MEAN LIFE OF 15200 KM. THIS SAMPLE WAS DRAWN FROM A POPULATION WHOSE MEAN IS 15150 KM AND STANDARD DEVIATION OF 1200 KM.
