Hello. I would like to ask a college statistics question.
Q. One hundred draws are made at random with replacement from the box [1,2,2,5].
The draws come out as follows:17 's, 54 's, 29 's. Fill in the blanks, using the options below; show work.
(a) For the _______, the observed value is 0.8 SEs above the expected value.
(b) For the _______, the obseved value is 1.33 SEs above the expected value.
Options (one will be left over):
sum of the draws
number of 1's
number of 2's
1 should be ¼ so it should be drawn 25 times
2 should be ½ so it should be drawn 50 times
5 should be ¼ so it should be drawn 25 times
S2=(2.25+.25+.25+6.25)/4=9/4=.25 so S=1.5
A. number of 2's
B. Sum of the draws (270-250=20 and 20/15=1.33)
