Answer:
The answer is (C)
Step-by-step explanation:
Sample size = 518
The number of green candies observed/counted is = 93
That's an approximated value for 18% of the 518 candies
18/100 × 518 = 93.24 ≅ 93
Note, the symbol ≅ means 'approximately equal to'
Since the candy company claims that the distribution of each color is exactly 20%, the expected frequency for green candies is:
20% of 518 = 20/100 × 518 = 103.6
That makes the answer (C)
Answer:
observed: 93 exp: 103.6
Step-by-step explanation:
To get the observed frequency, we simply look at the value in the column. In this case, it is 93 for the green group.
