3. The manufacturer of a patent medicine claimed that it was 90% effective in relieving an allergy for a period of 8 hours. In a sample of 200 people who had the allergy, the medicine provided relief for 160 people. It was determined whether the manufacturer's claim is legitimate at 0.01 level of significance. Null Hypothesis (H₂) Alternative Hypothesis (H₁) Parameter a 4. In an experiment on extrasensory perception (ESP), a subject in one room is asked to state the color (red or black) of a card chosen from a deck of 50 well-shuffled cards by an individual in another room. It is unknown to the subject how many red or black cards are in the deck. If the subject identifies 32 cards correctly, determine whether the results are significant at the 0.05 and 0.01 level of significance. Null Hypothesis (H₂) Alternative Hypothesis (H₁) C Parameter 5. An examination was given to two classes consisting of 40 and 50 students, respectively. In the first class, the mean grade was 74 with a standard deviation of 8; while in the second class, the mean grade was 78 with a standard deviation of 7. Is there a significant difference between the performance of the two classes at 0.05 and 0.01 level of significance. Null Hypothesis (H) Alternative Hypothesis (H) a Parameter
