For problems 4-5 the mean average is 207 and the standard deviation is 39.33 Please calculate Prob( x > 233) Please calculate Prob( 175 Ist sample proportion is 0.65 with sample size 220 2nd sample proportion is 0.59 with sample size 221 Samples come from DIFFERENT populations! Hypothesis test for equal proportions Please Sample #1 has mean - 796 : studDev = 151.24 and size NI = 94 Sample #2 has mean = 883.56 : studDev = 79.52 and size N2 - 89 Hypothesis test for equal means Please Sample of N-200 is divided equally into 2 groups of 100 Ist group is given the experimental treatment while the other group is given the regular treatment/placebo # of successes in first group is 48 # of successes in 2nd group is 45 Hypothesis test for equal proportions Please 95% confidence interval for the mean = 179 : studDev = 14.32 : sample size N= 102 95% confidence interval for the proportion = 0.14 with sample size N= 89 Random game of chance has 3 possible outcomes: LOSS, TIE, or WIN; WIN is twice as likely as a LOSS. LOSS is 3 times as likely as a TIE. What are the (respective) probabilities of WIN, LOSS, and TIE ?
