(Please provide 1. Ho and Ha, 2. The p-value or test-statistic, 3. the decision, (fail to reject or reject), 4. The conclusion (does the data support claim?)
1. In a recent study 5000 surveys were sent out and 717 were returned. Use a .01 significance level to test the claim that the return rate is LESS than 15%.
2. In football among 460 overtime games 252 were won by the team that won the coin toss. Test the claim that the team that wins the coin toss winning percentage is GREATER than 50%.

2. At the start of overtime in a National Football League game, a coin is flipped to determine which team will kick off and which will receive. The question of interest is how much advantage (if any) is given to the team that wins the coin flip at the start of the sudden death overtime period. In the overtime games played between 1974 and 2009, the winner of the coin flip won the game in 240 of the 428 games...

The P-value for a hypothesis test is shown. Use the P-value to decide whether to reject He when the level of significance is (a) a = 0.01, (b) a = 0.05, and (C) a = 0.10. P = 0.0695 (a) Do you reject or fail to reject He at the 0.01 level of significance? O A. Fail to reject H, because the P-value, 0.0695, is greater than a = 0.01. O B. Fail to reject H, because the P-value, 0.0695,...

(PLEASE PUT HO,HA, RIGHT/LEFT TAIL, TWO TAILS,CRITICAL VALUE, ALPHA,TEST-STATISTIC,P-VALUE,DECISION AND CONCLUSION) 1. Does aspirin reduce heart attacks? In a study 11037 males physicians were given aspirin daily and 139 experience a heart attack withing a 10 year period, while 11034 male physicians were given a placebo daily and 239 experienced a heart attack in the same 10 year period. Use a significance level of .05 to test the claim that daily use of aspirin reduces the proportion of those who...
