It is question 4-10

For problems 4-5 the mean average is 979 and the standard deviation is 146.85 Please calculate Prob( x > 1119) Please calculate Prob( 839 Sample #1 has mean = 395 : studDev = 39.50 and size N1 = 96 Sample #2 has mean = 438.45 : studDev = 61.38 and size N2 = 79 Hypothesis test for equal means Please Sample of N=150 is divided equally into 2 groups of 75 Ist group is given the experimental treatment while the other group is given the regular treatment/placebo # of successes in first group is 15 # of successes in 2nd group is 13 Hypothesis test for equal proportions Please Ist sample proportion is 0.56 with sample size 185 2nd sample proportion is 0.61 with sample size 190 Samples come from DIFFERENT populations! Hypothesis test for equal proportions Please 95% confidence interval for the mean = 329 : stndDev = 19.74 : sample size N= 206 95% confidence interval for the proportion = 0.13 with sample size N= 97
