Answer:
Significant difference of 0.20
Step-by-step explanation:
No of student = 20
No of fruits available =4
EAch student is independent of the other.
Hence theoretical probability that a student will choose a banana is=1/4=0.25.
But actual experiments showed that only 1 student selected banana out of 20
Experimental probability that a student will choose a banana is.=1/20 =0.05
The difference between the two = 0.25-0.05 = 0.20
Thus there is a significant difference between Experimental probability that a student will choose a banana and theorical probability that a student will choose a banana
-29 because negative plus positive = negative
Assuming the envelope consumption is proportional to the number of typists, you have ...
(12 dz)/36 = x/125
125*(12 dz)/36 = x = 41 2/3
An office of 125 typists would use 41 2/3 dozen envelopes per day.
