Need 1-7

uestions 1-7 are related to the followin A random sample of 6 patients visiting a family clinic was 23 14 13 25 43 1The sample mean waiting time is, 28 minutes 27 minutes 26 minutes 25 minutes 2 The deviation of the largest observation in the sample from the sample mean is, 17 minutes 16 minutes 15 minutes 14 minutes 3The sum of squares of the data is, 5304 5280 5256 5232 4The sum of squared deviations of the data is, 886 908 930 955 5The variance of the sample data is, 186.0 172.0 158.0 155.0 6 The waiting times deviate from the mean waiting time, on average, by, 12.45 minutes 12.57 minutes 12.95 minutes 13.64 minutes 7 The largest observation in the sample deviates from the 1.25 1.30 1.32 1.34

Solution

ANSWER: ACCORDING TO CHEGG Q AND A POLICY ONLY FIRST FOUR PARTS WILL BE ANSWERED AT A TIME, FOR FURTHER ANSWER TO PARTS ASK AS A SEPERATE QUESTION.

1) SAMPLE MEAN WAITING TIME = SUM OF ALL SAMPLES / NO OF OBSERVATIUONS = (23 + 14 + 13 + 44 + 25 + 43 ) / 6 = 27 AND HENCE THE OPTION IS B.

2) LARGEST OBSERVATION = 44

MEAN = 27

DIFFERENCE = 44 - 27 = 17, HENCE OPTION A IS RIGHT

3) SUM OF SQUARES OF DATA = (23) ^ 2 + ( 14) ^2 + (13) ^2 + (44) ^ 2 + (25) ^2+ (43) ^2 = 529 +196+ 169 + 1936 + 625 + 1849 = 5304 AND HENCE OPTION A IS RIGHT.

4) VARIANCE =ADDING (EACH OBSERVATION - SAMPLE MEAN )^ 2

VARIANCE = (23 - 27) ^ 2 + (14 -27) ^2 + ( 13 -27) ^2 + (44 -27) ^ 2 + (25 -27 ) ^2 + (43 - 27) ^ 2 = (4) ^2 + (13) ^2 + (14) ^ 2 + (17) ^ 2 + ( -2)^ 2 + (16) ^ 2 = 16 + 169 + 196 + 289 + 4 + 256 = 930 AND HENCE OPTION C IS RIGHT.
